The Spring Midwest Topology Seminar will be a two-day event, Saturday
April 28 and Sunday April 29 at Purdue University.

We have arranged a block of rooms at the Union Club Hotel (reserve by this
Friday, April 13, mention ``Midwest Topology Seminar'').

Some limited funds are available to support hotel and travel costs of
participants, especially for graduate students and junior faculty without
other support.  If you would like to apply for support, contact Ralph
Kaufmann ([log in to unmask]) as soon as possible. Please include an
estimate of your expenses. The deadline for applications is Thursday 
April 19. Decisions will be made  soon thereafter.

More information is available at the conference website:

This message was sent to you via the Geometry List, which announces conferences in geometry and closely related areas to over 1200 mathematicians worldwide.

At http://listserv.utk.edu/archives/geometry.html there are many functions available, including checking the archives since November 2005, changing your e-mail address or preferences, and joining/leaving the list. If you have problems that cannot be resolved at this website, send a message to [log in to unmask]

Before sending an announcement, please carefully read the following. Any announcements that are *not* about conferences (e.g. those about jobs, journals, books, etc.) will be rejected by the moderator without comment. To announce a geometry or closely related conference, send the announcement (including a conference web site if possible) to [log in to unmask] The moderator cannot edit your message; list members will receive the announcement as an e-mail from you EXACTLY as you submitted it. For example, if your submission starts with "Please post this on the geometry list" then your conference announcement will also begin with that statement. In order to keep down the volume of e-mail, only TWO announcements per conference will be approved by the moderator. The "subject" of your message should include the name of the conference and the number (first or second) of the announcement, e.g. Gauss Memorial Lectures in Geometry: Second Announcement. Please check that your announcement (especially the website) is correct. Corrections will be approved only in the most critical situations, e.g. if corrected information is not available on the website. If you send a submission from an e-mail address that is not subscribed to the geometry list then you will be sent an e-mail asking for confirmation. This feature is designed to thwart the hundreds of machine-generated spam that are sent to the list and would otherwise have to be manually blocked by the moderator.

The Geometry List is sponsored and maintained by the Mathematics Department, The University of Tennessee, Knoxville.
