Categorification via blocks of modular representations II
Vinoth Nandakumar, Gufang Zhao
Bernstein, Frenkel and Khovanov have constructed a categorification of tensor products of the standard representation of using singular blocks of category $\mathc…
Irreducible Components of Exotic Springer fibres II: The Exotic Robinson-Schensted Algorithm
Vinoth Nandakumar, Daniele Rosso, Neil Saunders
Kato's exotic nilpotent cone was introduced as a substitute for the ordinary nilpotent cone of type C with cleaner properties. The geometric Robinson-Schensted correspondence is ob…
Modular representations in type A with a two-row nilpotent central character
Galyna Dobrovolska, Vinoth Nandakumar, David Yang
We study the category of representations of in positive characteristic, whose p-character is a nilpotent whose Jordan type is the two-row partition (m+n,n).…
Categorification via blocks of modular representations for sl(n)
Vinoth Nandakumar, Gufang Zhao
Bernstein, Frenkel, and Khovanov have constructed a categorification of tensor products of the standard representation of , where they use singular blocks of categ…
Irreducible components of exotic Springer fibres
Vinoth Nandakumar, Daniele Rosso, Neil Saunders
Kato introduced the exotic nilpotent cone to be a substitute for the ordinary nilpotent cone of type C with cleaner properties. Here we describe the irreducible components of exoti…
Exotic t-structures for two-block Springer fibers
Rina Anno, Vinoth Nandakumar
We study the exotic t-structure on the derived category of coherent sheaves on two-block Springer fibre (i.e. for a nilpotent matrix of type (m+n,n) in type A). The exotic t-struct…
Stability conditions for Gelfand-Kirillov subquotients of category O
Vinoth Nandakumar
Recently, Anno, Bezrukavnikov and Mirkovic have introduced the notion of a "real variation of stability conditions" (which is related to Bridgeland's stability conditions), and con…
