- Abstract

 : Let  M(d,1) be the moduli space of stable sheaves on with Hilbert polynomial dm + 1. In this talk, we express the nef cone of M(d,1)  in terms of geometric divisors. Main idea is to use the Bridgeland wall-crossing and the Grothendieck-Riemann-Roch calculation. If times are allowed, we compute the BPS index by using Bridgeland wall-crossing
