Тема избитая, тем не менее имею вопрос:
- 14 февраля 2009 я подал опус в Adv. Math.
- 15 января 2010 я поинтересовался: во-первых, что означает наблюдаемое в их онлайновой системе "status date: September 20, 2009", а во-вторых, как там вообще дела.
- на первый вопрос ответа не получил, на второй вопрос получил ответ что "We contacted the referee once again today regarding this manuscript. We have also contacted the Editor to recommend an alternate referee to review this paper, in case the initial reviewer fails to respond".
- 15 апреля 2010 я поинтересовался: как там вообще дела.
- получил ответ что "We contacted the referee once again today regarding this manuscript. We have also contacted the Editor to recommend an alternate referee to review this paper, in case the initial reviewer fails to respond."
Вопрос: что делать и кто виноват?
Варианты ответа:
1. ничего, смиренно ждать (потому что, во-первых, я неизбалован публикациями в приличных местах, а вроде как Adv. Math. приличное, может все-таки выгорит; а во-вторых, может злостный рецензент образумился и в эту минуту рецензирует опус, и если его отозвать получится что он тратил время зря);
2. забрать опус (потому что нефиг). | | Friday, December 4th, 2009 | | 9:37 am |
Интересуюсь: вот это вот - Koji Nagata, There is no axiomatic system for the quantum theory, International Journal of Theoretical Physics 48 (2009), 3532-3536 http://dx.doi.org/10.1007/s10773-009-0158-z - херня полная, или просто так замысловато сформулировано? | | Tuesday, August 4th, 2009 | | 6:57 pm |
Хи-хи, неподготовленный emacs (без кустомизированного .ispellа) предлагает заменить Koszulity на sexuality. | | Monday, July 27th, 2009 | | 2:07 pm |
А изложена ли где-нибудь аккуратно двумерная механика? Скажем, какой будет Ньютоновский закон тяготения в двумерном мире, N-body problem, и так далее?

Are there examples of binary quadratic operads which are not Koszul but whose Poincare series is inverse to the Poincare series of the dual operad, like in the celebrated Ginzburg-Kapranov criterion? | | Wednesday, January 21st, 2009 | | 1:43 pm |

Berezin
A book about Berezin (MCCME, 2009): http://justpasha.org/math/links/files/berlife-1204.pdf . This is an expanded version of the English book (World Sci., 2007), which was floating around for a while.
Update Dec 27, 2008: раздача окончена до лучших времен, спасибо за внимание, кто не спрятался я не виноват, etc. | | Sunday, September 21st, 2008 | | 9:52 pm |

Производственное. III
Вот люди, трудовой карьере которых я завидую. 1. Валерий Фабрикант. После 10 лет работы в Concordia University ему это несколько надоело, и он перестрелял часть профессорско-преподавательского состава. Отбывает пожизненное заключение до 2018 года, пишет 1-2 статьи в год с affiliation "Prisoner #167932D, Archambault Jail, Ste-Anne-des-Plaines, Quebec, Canada J0N 1H0". 2. Неизвестный гражданин из города Дельфта. У неизвестного гражданина такая форма сумасшествия: он считает себя профессором университета, и впадает в буйное расстройство если в этом сомневаются. Медики постановили что лучше его не волновать. Ему снимают кабинет в одном из зданий Delft Technical University, деньги на аренду покрывает медицинская страховка, он ходит туда как на работу, сидит там, чего-то делает, счастлив. | | Saturday, March 1st, 2008 | | 11:13 pm |

Does there exist a finite-dimensional commutative associative algebra which has an infinite number of non-isomorphic modules of a fixed finite dimension? | | Friday, January 25th, 2008 | | 7:07 pm |
Flowers for Algernon. X
Consider the following statement: there are 3 3x3 traceless matrices X, Y, Z such that 7 matrices XYZ, XZY, YXZ, YZX, ZXY, ZYX and (Tr(XYZ) - Tr(XZY))E (E is the identity matrix) are linearly independent. Play with computer shows that apparently any 3 3x3 traceless matrices in general position are such. I would like to have an elegant (algebro-geometric, linear-algebraic, whatever) proof. Such things appear in an attempt to describe Poisson structures on the Lie algebra sl_n(A). ( xposted to liealgebras yahoo group) | | Thursday, December 20th, 2007 | | 5:55 pm |

Работники из отдела роботики соорудили витрину, в которой выставлены маленькие фигуры девы Марии, овечек, волхвов и прочие аксессуары. Одного из роботов освободили от переноски кусочков ДНК с места на место, и он теперь переносит новорожденного Иисуса. Это интереснее, чем было у финансовых аналистов, так что прогресс в моей трудовой карьере налицо.

How Tarski's monsters constructed by Olshanskii (groups all whose proper subgroups are infinite cyclic), as well as their look-alikes, behave with respect to group identities? I believe they both could have nontrivial identities, and could not. Monsters having identities were seemingly constructed by Atabekyan (announced in a short paper in Vestnik MGU with a full text deposited at VINITI in 1986-1987 - I haven't seen neither of them). | | Monday, October 8th, 2007 | | 2:54 pm |
Soft Revue (probably not a Revue, but Soft anyway). V
I want to have a finer granularity of perl architecture-dependent modules then those provided at perl binary compile time and via the standard perl mechanism. Specifically, I am running some perl thingie on a bunch of machines which are all Linux-Intel, so everything supposed to be binary-compatible (i386-linux-whatever). Alas, one of the perl modules (written in C++) compiled against blas/lapack libraries which are highly CPU-dependent. So I place different binaries of this perl module compiled against different blas/lapack's for different CPUs somehow under the perl modules tree, and then do something like that:
BEGIN
{
# description of CPU in /proc/cpuinfo =>
# short symbolic description used in perl modules tree
use constant CPU => { 'Intel(R) Pentium(R) D CPU' => 'D',
'Intel(R) Xeon(TM) CPU' => 'Xeon'};
my $arch;
open (F, '< /proc/cpuinfo') || die ('unable to open /proc/cpuinfo');
for (<F>)
{
if (/^model name\s+:\s*(.*)\s+[0-9]\.[0-9]+GHz/)
{
$arch = CPU->{$1};
die ("unknown CPU type: $1 ") if (! defined ($arch));
last;
}
}
close (F);
die ('cannot determine CPU type') if (! defined ($arch));
push (@INC, "/tra/la/la/lib/perl/$arch");
}
Perhaps I am inventing a square wheel? | | Saturday, September 29th, 2007 | | 4:12 pm |
Jonathan Borwein and David Bailey, Mathematics by Experiment. Plausible Reasonings in the 21st Century, A.K. Peters, 2004, 288 pp.
I was disappointed by this book. I got an impression that this is a well-known and highly acclaimed book in the field and was eager to read it. May be I misinterpreted what "the field" really is. Sure, my negative impression was caused largely by not standing up to my high expectations.
When I finished to read this book about a month ago, I intended to write a long review analyzig it fallacies with concrete examples, etc., but time has passed and my enthusiasm weared off.
First, the book pretends to be much more than it really is - to cover the whole mathematics and to present new paradigms in it, but in reality it is merely about some aspects of mmm... computational number theory (is it the right name?), like calculation of digits of pi and such curiosities and frivolities.
Second, it seems to be more a bunch of loosely related essays and observations, sometimes contradicting one another, than a coherently written treatise with unifying ideas and themes.
There are quite a few misprints.
Granted, I learned a couple of interesting things from it: how computer algebra systems evaluate certain expressions, or how one can compute digits of some numbers (notably pi with which authors are obviously obsessed) in a not consecutive way.
It is printed very nicely, and can adore a bookshelf.
I doubt I will be willing to read its sequel (this book supposed to be the first volume in a two-volumes set), or anything else from the authors in the foreseable future, for that matter. | | Monday, September 24th, 2007 | | 4:33 pm |

2. (Lack of) naming scheme. Names of my computers since approximately 1997 (what was before 1997, history does not tell): crazycow, poor, oldcrap, wincrap, dustpuppy, puffy, humpty-dumpty, bigbug, chronop, goblin, zebra. I really don't understand why there were so many of them. Update Oct 2, 2008: The latest machine was named puudly. 3. Microsoft-plagued ISP. At certain moment, I started to notice multiple UDP broadcat requests to the port 67 on the part of my home network betwen the gateway machine and ADSL modem. A typical tcpdump output looks like this:
20:29:01.063780 IP (tos 0x0, ttl 128, id 6, offset 0, flags [none], proto UDP (1
7), length 328) 0.0.0.0.bootpc > 255.255.255.255.bootps: [udp sum ok] BOOTP/DHCP
, Request from 00:02:96:05:a5:6c (oui Unknown), length 300, xid 0xfeacebc9, Flag
s [none] (0x0000)
Client-Ethernet-Address 00:02:96:05:a5:6c (oui Unknown)
Vendor-rfc1048 Extensions
Magic Cookie 0x63825363
DHCP-Message Option 53, length 1: Discover
NOAUTO Option 116, length 1: Y
Client-ID Option 61, length 7: ether 00:02:96:05:a5:6c
Requested-IP Option 50, length 4: 169.254.29.32
Hostname Option 12, length 8: "DFYW8G1J"
Vendor-Class Option 60, length 8: "MSFT 5.0"
Parameter-Request Option 55, length 11:
Subnet-Mask, Domain-Name, Default-Gateway, Domain-Name-Server
Netbios-Name-Server, Netbios-Node, Netbios-Scope, Router-Discovery
Static-Route, Option 249, Vendor-Option
Neither of the reported MAC addresses belong to any device on my home network. My understanding of how PPP works is rather vague, but the magic acronym "MSFT" and some googling (ah, yes) suggest that this is a Windows ISP machine sitting on the 10.*.*.* network (those connecting ADSL modem with ISP) emitting these bogus DHCP requests. I was too lazy to perform the full scan of the 10.*.*.* network (it would take ages, and I am not sure it will produce any result), so I decided to install a dhcp server, trying to provide a lease to this idiotic machine and to catch it that way. Unfortunately (or rather fortunately as there are more interesting things to do) since I did that, those DHCP requests stopped entirely. |
