A mod p local Langlands correspondence is known for GL_2(Q_p) and believed to exist between mod p representations of the absolute Galois group of F and certain mod p representations of GL_n(F) for arbitrary F and n. A major obstacle to the study of the correspondence is that the supersingular mod p representations of GL_n(F), which are the building blocks of the mod p representation theory of this group, are very poorly understood. After an introduction to the mod p representation theory of GL_n(F), we will discuss recently discovered obstacles to the understanding of the supersingular representations, as well as what is known. </td> </table> <HR NOSHADE SIZE=3 WIDTH=100%> <h2><font color="#2244bb">Schedule</font><h2> <TABLE WIDTH=1040 BORDER=1 BORDERCOLOR="#000000" CELLPADDING=4 CELLSPACING=1 STYLE="page-break-inside: avoid"> <COL WIDTH=170> <COL WIDTH=220> <COL WIDTH=650> <THEAD> <TR> <TD WIDTH=170> <P><b> Date</b></P> </TD> <TD WIDTH=220> <P><b> Speaker</b></P> </TD> <TD WIDTH=650> <P><b> Title</b></P> </TD> </TR> </THEAD> <TBODY> <TR> <TD WIDTH=170> <p> March 21, 2012</P> </TD> <TD WIDTH=220> <P>Dima Gourevitch<br>(Weizmann Institute)</P> </TD> <TD WIDTH=650> <P> <i>Degenerate Whittaker models for real reductive groups</i> (<A HREF="http://www.math.bgu.ac.il/~tyomkin/AGeNT_Spring2012/Dima.html">announcement</A>)</P> </TD> </TR> <TR> <TD WIDTH=170> <p> March 28, 2012</P> </TD> <TD WIDTH=220> <P>Matan Prezma<br>(Ben-Gurion University)</P> </TD> <TD WIDTH=650> <P> <i>Introduction to abstract homotopy theory</i> (<A HREF="http://www.math.bgu.ac.il/~tyomkin/AGeNT_Spring2012/Matan.html">announcement</A>)</P> </TD> </TR> <TR> <TD WIDTH=170> <p> April 4, 2012</P> </TD> </TD> <TD WIDTH=220> <P><font color=red>No seminar</font><br></P> </TD> <TD WIDTH=650> <P> <i>No seminar this week due to Passover vacation</i> </TD> </TR> <TR> <TD WIDTH=170> <p> April 11, 2012</P> </TD> <TD WIDTH=220> <P><font color=red>No seminar</font><br></P> </TD> <TD WIDTH=650> <P> <i>No seminar this week due to Passover vacation</i> </TD> </TR> <TR> <TD WIDTH=170> <p> April 18, 2012</P> </TD> <TD WIDTH=220> <P>Santosha Pattanayak<br>(Weizmann Institute)</P> </TD> <TD WIDTH=650> <P> <i>Projective Normality of G.I.T. quotient varieties modulo finite solvable groups and Weyl groups</i> (<A HREF="http://www.math.bgu.ac.il/~tyomkin/AGeNT_Spring2012/Santosha.html">announcement</A>)</P> </TD> </TR> <TR> <TD WIDTH=170> <p> April 25, 2012</P> </TD> <TD WIDTH=220> <P><font color=red>No seminar</font></P> </TD> <TD WIDTH=650> <P> <i>No seminar this week due to Memorial Day</i> </TD> </TR> <TR> <TD WIDTH=170> <p> May 2, 2012</P> </TD> <TD WIDTH=220> <P>Dan Abramovich<br>(Brown Universtity)</P> </TD> <TD WIDTH=650> <P> <i>Logarithmic Gromov-Witten invariants</i> (<A HREF="http://www.math.bgu.ac.il/~tyomkin/AGeNT_Spring2012/Dan.html">announcement</A>)</P> </TD> </TR> <TR> <TD WIDTH=170> <p> May 9, 2012</P> </TD> <TD WIDTH=220> <P>Michael Schein<br>(Bar Ilan University)</P> </TD> <TD WIDTH=650> <P> <i>The mod p local Langlands correspondence and supersingular representations of GL_2(F)</i> (<A HREF="http://www.math.bgu.ac.il/~tyomkin/AGeNT_Spring2012/Michael.html">announcement</A>)</P> </TD> </TR> <TR> <TD WIDTH=170> <p> May 16, 2012</P> </TD> <TD WIDTH=220> <P>TBA<br>(TBA)</P> </TD> <TD WIDTH=650> <P> <i>TBA</i> (<A HREF="http://www.math.bgu.ac.il/~tyomkin/AGeNT_Spring2012/TBA.html">announcement</A>)</P> </TD> </TR> <TR> <TD WIDTH=170> <p> May 23, 2012</P> </TD> <TD WIDTH=220> <P>Matan Prezma<br>(Ben-Gurion University)</P> </TD> <TD WIDTH=650> <P> <i>TBA</i> (<A HREF="http://www.math.bgu.ac.il/~tyomkin/AGeNT_Spring2012/TBA.html">announcement</A>)</P> </TD> </TR> <TR> <TD WIDTH=170> <p> May 30, 2012</P> </TD> <TD WIDTH=220> <P>TBA<br>(TBA)</P> </TD> <TD WIDTH=650> <P> <i>TBA</i> (<A HREF="http://www.math.bgu.ac.il/~tyomkin/AGeNT_Spring2012/TBA.html">announcement</A>)</P> </TD> </TR> <TR> <TD WIDTH=170> <p> June 6, 2012</P> </TD> <TD WIDTH=220> <P>Liran Shaul<br>(Ben-Gurion University)</P> </TD> <TD WIDTH=650> <P> <i>TBA</i> (<A HREF="http://www.math.bgu.ac.il/~tyomkin/AGeNT_Spring2012/TBA.html">announcement</A>)</P> </TD> </TR> <TR> <TD WIDTH=170> <p> June 13, 2012</P> </TD> <TD WIDTH=220> <P>Pierre Dèbes<br>(University of Lille)</P> </TD> <TD WIDTH=650> <P> <i>Galois extensions of function fields and the Tchebotarev property</i> (<A HREF="http://www.math.bgu.ac.il/~tyomkin/AGeNT_Spring2012/Pierre.html">announcement</A>)</P> </TD> </TR> <TR> <TD WIDTH=170> <p> June 20, 2012</P> </TD> <TD WIDTH=220> <P>TBA<br>(TBA)</P> </TD> <TD WIDTH=650> <P> <i>TBA</i> (<A HREF="http://www.math.bgu.ac.il/~tyomkin/AGeNT_Spring2012/TBA.html">announcement</A>)</P> </TD> </TR> <TR> <TD WIDTH=170> <p> June 27, 2012</P> </TD> <TD WIDTH=220> <P>TBA<br>(TBA)</P> </TD> <TD WIDTH=650> <P> <i>TBA</i> (<A HREF="http://www.math.bgu.ac.il/~tyomkin/AGeNT_Spring2012/TBA.html">announcement</A>)</P> </TD> </TR> </TBODY> </TABLE> </font> </body> </font> </html>
