Local Langlands functoriality for Yu's supercuspidals II: Fargues--Scholze's parametrization

Sean Cotner, Tony Feng

This is the second of two papers dedicated to the explicit computation of the Fargues--Scholze correspondence. We compute the Tate cohomology of cuspidal representations arising fr…

Local Langlands functoriality for Yu's supercuspidals I: Kaletha's parametrization

Sean Cotner, Tony Feng

This is the first of two papers dedicated to the explicit computation of the Fargues--Scholze correspondence. In this first part, we construct (inspired by, and extending, Kaletha'…

Derived structures in the Langlands Correspondence

Tony Feng, Michael Harris

We survey several recent examples of derived structures emerging in connection with the Langlands correspondence. Cases studies include derived Galois deformation rings, derived He…

Geometric Langlands duality for periods

Tony Feng, Jonathan Wang

We study conjectures of Ben-Zvi--Sakellaridis--Venkatesh that categorify the relationship between automorphic periods and -functions in the context of the Geometric Langlands eq…

Modular functoriality in the Local Langlands Correspondence

Tony Feng

We develop a theory of Smith--Treumann localization in the context of Fargues-Scholze's Geometrization of the Local Langlands Correspondence. We then apply this theory to prove som…

Mirror symmetry and the Breuil-Mézard Conjecture

Tony Feng, Bao Le Hung

The Breuil-Mézard Conjecture predicts the existence of hypothetical "Breuil-Mezard cycles" in the moduli space of mod Galois representations of $\mathrm{Gal}(\overline{\mathbb{…
