Torsion-vanishing for Siegel modular varieties via supercuspidal congruences

Ana Caraiani, Sug Woo Shin

We prove that the generic part of the cohomology of Siegel modular varieties with torsion coefficients is concentrated above the middle degree, under a suitable notion of genericit…

Local Intertwining Relations and Co-tempered -packets of Classical Groups

Hiraku Atobe, Wee Teck Gan, Atsushi Ichino +3

The local intertwining relation is an identity that gives precise information about the action of normalized intertwining operators on parabolically induced representations. We pro…

Recent progress on Langlands reciprocity for : Shimura varieties and beyond

Ana Caraiani, Sug Woo Shin

The goal of these lecture notes is to survey progress on the global Langlands reciprocity conjecture for over number fields from the last decade and a half. We high…

The stable trace formula for Igusa varieties, II

Alexander Bertoloni Meli, Sug Woo Shin

Assuming the trace formula for Igusa varieties in characteristic p, which is known by Mack-Crane in the case of Hodge type with good reduction at p, we stabilize the formula via Ka…

The stable trace formula for Shimura varieties of abelian type

Mark Kisin, Sug Woo Shin, Yihang Zhu

We express the Frobenius-Hecke traces on the compactly supported cohomology of a Shimura variety of abelian type in terms of elliptic parts of stable Arthur-Selberg trace formulas…

Congruences of algebraic automorphic forms and supercuspidal representations

Jessica Fintzen, Sug Woo Shin

Let be a connected reductive group over a totally real field which is compact modulo center at archimedean places. We find congruences modulo an arbitrary power of p betwee…

Asymptotic behavior of supercuspidal representations and Sato-Tate equidistribution for families

Ju-Lee Kim, Sug Woo Shin, Nicolas Templier

We establish properties of families of automorphic representations as we vary prescribed supercuspidal representations at a given finite set of primes. For the tame supercuspidals…

Patching and the p-adic Langlands program for GL(2, Q_p)

Ana Caraiani, Matthew Emerton, Toby Gee +3

We present a new construction of the p-adic local Langlands correspondence for GL(2, Q_p) via the patching method of Taylor--Wiles and Kisin. This construction sheds light on the r…

Asymptotics and local constancy of characters of p-adic groups

Ju-Lee Kim, Sug Woo Shin, Nicolas Templier

In this paper we study quantitative aspects of trace characters of reductive -adic groups when the representation varies. Our approach is based on the local constancy…

Families of L-functions and their Symmetry

Peter Sarnak, Sug-Woo Shin, Nicolas Templier

In [90] the first-named author gave a working definition of a family of automorphic L-functions. Since then there have been a number of works [33], [107], [67] [47], [66] and espec…

Patching and the p-adic local Langlands correspondence

Ana Caraiani, Matthew Emerton, Toby Gee +3

We use the patching method of Taylor--Wiles and Kisin to construct a candidate for the p-adic local Langlands correspondence for GL_n(F), F a finite extension of Q_p. We use our co…
