Wall-crossing formulae for algebraic surfaces with $q>0$

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/150356We extend the ideas of Friedman and Qin (Flips of moduli spaces and transition formulae for Donaldson polynomial invariants of rational surfaces) to find the wall-crossing formulae for the Donaldson invariants of algebraic surfaces with geometrical genus zero, positive irregularity and anticanonical divisor effective, for any wall $ζ$ with $l_ζ=(ζ\sp{2}-p_1)/4$ being zero or one.Latex2e, 20 pagesAlgebraic GeometryWall-crossing formulae for algebraic surfaces with $q>0$text
