Subject: new Hopf listings From: Mark Hovey Date: 10 Dec 1999 11:15:48 -0500 And yet another two more. This is the 100th announcement I have made! Mark Hovey New papers uploaded to hopf between 12/9/99 and 12/10/99. 1. http://hopf.math.purdue.edu/cgi-bin/generate?/pub/Dugger/smod Title: Replacing Model Categories with Simplicial Ones Author: Daniel Dugger Email: ddugger@math.purdue.edu Abstract: We show that model categories of a very large class can be replaced up to Quillen equivalence by simplicial model categories. 2. http://hopf.math.purdue.edu/cgi-bin/generate?/pub/Giambalvo-Peterson/DicksonAGen A-Generators for Ideals in the Dickson Algebra by V. Giambalvo and F. P. Peterson vince@math.uconn.edu fpp@math.mit.edu The Dickson Algebra $D_q$ on $q$-variables is the algebra of invariants of the action of the mod-2 general linear group on a polynomial algebra in $q$-variables. We study the structure of certain ideals in this algebra as a module over the Steenrod Algebra $\A$, and develop methods to determine which elements are hit by Steenrod operations. This allows us to display a very small set of $\A$-generators for these ideals and show that the set is minimal in some cases. We include a minimal set of generators for $D_5$. ---------------------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.

To get the papers listed above, point your WWW client (Mosaic, Netscape) to the URL listed. The general Hopf archive URL is http://hopf.math.purdue.edu There are links to conference announcements, Purdue seminars, and other math related things on this page as well. The largest archive of math preprints is at http://xxx.lanl.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 xxx, send e-mail to math@xxx.lanl.gov with subject line "subscribe" (without quotes), and with the body of the message "add AT" (without quotes). You can also access Hopf through ftp. Ftp to hopf.math.purdue.edu, and login as ftp. Then cd to pub. Files are organized by author name, so papers by me are in pub/Hovey. If you want to download a file using ftp, you must type binary before you type get . To put a paper of yours on the archive, cd to /pub/incoming. Transfer the dvi file using binary, by first typing binary then put You should also transfer an abstract as well. Clarence has explicit instructions for the form of this abstract: see http://hopf.math.purdue.edu/pub/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@math.purdue.edu telling him what you have uploaded. I am solely responsible for these messages---don't send complaints about them to Clarence. Thanks to Clarence for creating and maintaining the archive.
