blowup formulas for virtual sheaf-theoretic invariants on projective surfaces
abstract:
for a smooth projective surface x, natural objects of study are its moduli spaces of (semi-) stable coherent sheaves. in rank one, their structural invariants are well-understood, starting with g\"{o}ttsche's famous formula for the betti numbers of the hilbert schemes of points of x in terms of the betti numbers of x itself. even for rank two
