Real cohomology groups of the space of nonsingular curves of degree 5 in $\bf{CP}^2$

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/61462We construct a modification of Vassiliev's method of calculating cohomology groups of spaces of nonsingular algebraic hypersurfaces. We use this modified method to calculate the real cohomology groups of the space of nonsingular plane quintics.version 4, some more proofs added, some more errors correctedAlgebraic TopologyAlgebraic GeometryReal cohomology groups of the space of nonsingular curves of degree 5 in $\bf{CP}^2$text
