Tits groups of affine Weyl groups
Radhika Ganapathy
Let be a connected, reductive group over a non-archimedean local field . Let be the completion of the maximal unramified extension of contained in a separable…
The center of Hecke algebras of types
Reda Boumasmoud, Radhika Ganapathy
We describe the center of the Hecke algebra of a type attached to a Bernstein block under some hypothesis. When is a connected reductive group over non-archimedean local fi…
Tits groups of Iwahori-Weyl groups and presentations of Hecke algebras
Radhika Ganapathy, Xuhua He
Let be a connected reductive group over a non-archimedean local field and be an Iwahori subgroup of . Let is the -th Moy-Prasad filtration subgroup of $I…
A Hecke algebra isomorphism over close local fields
Radhika Ganapathy
Let be a split connected reductive group over . Let be a non-archimedean local field. With $K_m: = Ker(G(\mathfrak{O}_F) \rightarrow G(\mathfrak{O}_F/\mathfrak{…
Congruences of parahoric group schemes
Radhika Ganapathy
Let be a non-archimedean local field and let be a torus over . With $\cT^{NR}$ denoting the Néron-Raynaud model of , a result of Chai and Yu asserts that the model $\…
Explicit construction of Ramanujan bigraphs
Cristina Ballantine, Brooke Feigon, Radhika Ganapathy +3
We construct explicitly an infinite family of Ramanujan graphs which are bipartite and biregular. Our construction starts with the Bruhat-Tits building of an inner form of $SU_3(\m…
On twisted exterior and symmetric square -factors
Radhika Ganapathy, Luis Lomelí
We establish the existence and uniqueness of twisted exterior and symmetric square -factors in positive characteristic by studying the Siegel Levi case of generalized spinor gro…
The local Langlands correspondence for GSp_4 over local function fields
Radhika Ganapathy
We prove the local Langlands correspondence for GSp_4(F), where F is a non-archimedean local field of positive characteristic with residue characteristic > 2.
