## Fourier transform of equivariant perverse sheavesThe 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.

## Construction of supercuspidal representationsSpeaker: Kam-Fai Tam (Max-Planck-Institut für Mathematik, Bonn) Title: Construction of supercuspidal representations Location: Hilbert Seminar Room (MS 337) Time: Thursday, April 5, 14:00--15:00 Abstract: Given a supercuspidal representation of GL_2 over a p-adic field or the group U_2 of 2-by-2 unitary matrices relative to a quadratic p-adic 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 Event Type: |

## Final comments and edits of the paperDiscussion 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_.

## Various TwistsWe'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. Event Date: Thursday, March 15, 2018 - 09:00 to 11:00 Event Type: |
