Divisorial contractions in dimension three which contract divisors to compound A

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/60176We deal with a divisorial contraction in dimension 3 which contracts its exceptional divisor to a cA_1 point. We prove that any such contraction is obtained by a suitable weighted blow-up.23 pagesAlgebraic Geometry14E30Divisorial contractions in dimension three which contract divisors to compound A_1 pointstext
