Positive Populations
Vadim Schechtman, Alexander Varchenko
A positive structure on the varieties of critical points of master functions for KZ equations is introduced. It comes as a combination of the ideas from classical works by G.Luszti…
Perverse sheaves over real hyperplane arrangements II
Mikhail Kapranov, Vadim Schechtman
Let H be an arrangement of hyperplanes in R^n and Perv(C^n,H) be the category of perverse sheaves on C^n smooth with respect to the stratification given by complexified flats of H.…
Contingency Tables with Variable Margins (with an Appendix by Pavel Etingof)
Mikhail Kapranov, Vadim Schechtman
Motivated by applications to perverse sheaves, we study combinatorics of two cell decompositions of the symmetric product of the complex line, refining the complex stratification b…
Shuffle algebras and perverse sheaves
Mikhail Kapranov, Vadim Schechtman
We relate shuffle algebras, as defined by Nichols, Feigin-Odesskii and Rosso, to perverse sheaves on symmetric products of the complex line (i.e., on the spaces of monic polynomial…
