The Fourier transform we're using is taken from Kashiwara and Shapira by way of Schurmann, and has the vanishing cycles functor built in. Today we're working on establishing and documenting the main properties of this functor.

Title: Construction of supercuspidal representations
Location: Hilbert Seminar Room (MS 337)
Time: Thursday, April 5, 14:0015:00
Abstract: Given a supercuspidal representation of GL_2 over a padic field or the group U_2 of 2by2 unitary matrices relative to a quadratic padic field extension, we explain how to use the internal structure of its Langlands parameter to construct a underlying type of this representation. (If time permits, we will also cover a construction of discrete series representations.)
Event Date: Thursday, April 5, 2018  14:00 to 15:00

Discussion of the final touches on combined paper (erstwhile, Parts 1 and 2), now called _Arthur packets by way of microlocal vanishing cycles of perverse sheaves, with examples_.
Event Date: Thursday, March 29, 2018  09:00 to 11:00

We've encountered three interesting twists: one that appears when we normalise the microlocal vanishing cycles functor; one that appears when we relate the Fourier transform to microlocal vanishing cycles; and one that appears when we compare Moeglin's normalisation of Arthur packets with Arthur's normalisation. Today we wonder why they all coincide in our examples, and try to understand how they relate more generally.

Title: Abelian varieties with everywhere good reduction over certain real quadratic fields.
Abstract: In this talk, we give a complete classification of all abelian varieties with everywhere good reduction over the real quadratic fields of discriminant 53, 61 and 73. This extends previous results of Fontaine and Schoof.
