Subject: new Hopf listings From: Mark Hovey Date: 19 Mar 2007 07:35:40 -0400 I am running late this month. There are 3 new papers this time, fron BrownR, Muro, and SmithL. Mark Hovey New papers appearing on hopf between 2/3/07 and 3/19/07 1. http://hopf.math.purdue.edu/cgi-bin/generate?/BrownR/glob-gpds2 AUTHOR: Ronald Brown AUTHOR ADDRESS: School of Computer Science, University of Wales, Dean St., Bangor, Gwynedd, LL57 1UT, UK; TITLE: A new higher homotopy groupoid: the fundamental globular omega-groupoid of a filtered space MSC Classification:18D10, 18G30, 18G50, 20L05, 55N10, 55N25. KEY WORDS: filtered space, higher homotopy van Kampen theorem, cubical singular complex, free globular groupoid xxxLANL archive: math.AT/0702677 2 eps files, 19 pages ABSTRACT: We show that the graded set of filter homotopy classes rel vertices of maps from the n-globe to a filtered space may be given the structure of globular omega--groupoid. The proofs use an analogous fundamental cubical omega--groupoid due to the author and Philip Higgins. This method also relates the construction to the fundamental crossed complex of a filtered space, and this relation allows the proof that the crossed complex associated to the free globular omega-groupoid on one element of dimension n is the fundamental crossed complex of the n-globe. 2. http://hopf.math.purdue.edu/cgi-bin/generate?/Muro/tcwm6 Title: A triangulated category without models Author(s): Fernando Muro Author's mailing address: Universitat de Barcelona, Facultat de Matemàtiques, Departament d'Àlgebra i Geometria, Gran Via de les Corts Catalanes 585, 08007 Barcelona, Spain AMS classification number: 18E30, 55P42, 16E40 Abstract: We exhibit a triangulated category which is neither the stable category of a Frobenius category nor a full triangulated subcategory of the homotopy category of a stable model category. 3. http://hopf.math.purdue.edu/cgi-bin/generate?/SmithL/13a50 (This abstract was written by Mark) Reference list on Invariant Theory Author: Larry Smith AMS Code: 13A50 Invariant Theory Address: Mathematisches Institut Bunsenstrasse 3--5 D 37073 Goettingen Federal republic of germany Abstract: This is a list of references in invariant theory. The .tex file is included so that one can import references into a document. The journals.tex file includes macros for journals. ---------------------Instructions----------------------------- To subscribe or unsubscribe to this list, send a message to Don Davis at dmd1@lehigh.edu with your e-mail address and name. Please make sure he is using the correct e-mail address for you. To see past issues of this mailing list, point your WWW browser to http://math.wesleyan.edu/~mhovey/archive/ If this doesn't work or is missing a few issues, try http://www.lehigh.edu/~dmd1/algtop.html which also has the other messages sent to Don's list. To get the papers listed above, point your Web browser to the URL listed. The general Hopf archive URL is http://hopf.math.purdue.edu There is a web form for submitting papers to Hopf on this site as well. You should submit an abstract as well. Clarence has explicit instructions for the form of this abstract: see http://hopf.math.purdue.edu/new-html/submissions.html In particular, your abstract is meant to be read by humans, so should be as readable as possible. I reserve the right to edit unreadable abstracts. You should then e-mail Clarence at wilker at math.purdue.edu telling him what you have uploaded. The largest archive of math preprints is at http://arxiv.gov There is an algebraic topology section in this archive. The most useful way to browse it or submit papers to it is via the front end developed by Greg Kuperberg: http://front.math.ucdavis.edu To get the announcements of new papers in the algebraic topology section at the arXiv, send e-mail to math@arxiv.org with subject line "subscribe" (without quotes), and with the body of the message "add AT" (without quotes). I am solely responsible for these messages---don't send complaints about them to Clarence. Thanks to Clarence for creating and maintaining the archive.
