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…
Quiver varieties and crystals in symmetrizable type via modulated graphs
Vinoth Nandakumar, Peter Tingley
Kashiwara and Saito have a geometric construction of the infinity crystal for any symmetric Kac-Moody algebra. The underlying set consists of the irreducible components of Lusztig'…
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…
