Please come and provide your suggestions, or send your suggestions in case you can't make it. Also let us know if you would like to be taken off this list, or if you know of someone who would like to join it. The algebra seminar will continue to convene Mondays at 4 in Kassar 105. It is organized by Steve Lichtenbaum and Mike Rosen. The algebraic geometry seminar on Fridays at 3 in Kassar 205. It will be organized by some subset of Nathan, Brendan, Melody and me.

Abstract:
+
== Weekly schedule template ==
We discuss some results on the existence and nonexistence of covers of curves with prescribed tame ramification in positive characteristic, We consider construction of covers in positive characteristic using stable reduction of covers in characteristic zero. This yields results on Hurwitz curves.

* Jeff Hoffstein will be teaching a graduate course this semester that may be of interest to some junior participants. To quote: <blockquote>
+
Hi Everyone,
+
 
+
I'll be giving what is essentially a second year graduate class in analytic algebraic number theory.  It will start this coming Tuesday and will be held, at the moment, from 2:30 - 3:50 on Tuesdays and Thursdays in Kassar 105 in the math dept on the corner of George and Thayer.  The class will develop the basic theory of algebraic number fields, and present Hecke's approach to obtaining the analytic continuation and functional equation of the Dedekind zeta function.  Please let me know if you might be interested in attending.  If there is sufficient interest I will move the class to ICERM.
+
 
+
--Jeff Hoffstein

</blockquote>
+
* There will be an AGNES (Algebraic Geometry Northeastern Series) conference October 2-4, immediately after the first thematic workshop; this includes a public lecture Friday evening by Jordan Ellenberg. Those wishing to attend are asked to register [http://www.agneshome.org/brown-2015-1 here] as soon as possible.
+
* ICERM is soliciting proposals for their new [https://icerm.brown.edu/participate/ Collaborate@ICERM program], in which groups of 3-6 gather for focused research. Applications from collaborations originating from semester programs are specially encouraged!
