A pencil of Enriques surfaces of index one with no section

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/109138Mondromy and deformation-and-specialization arguments are used to produce a pencil of Enriques surfaces with no section and index one. The same technique completes the proof that the witness curves in "Rational connectivity ..." depend on the relative dimension.5 pages, posting of older preprintAlgebraic Geometry14G05; 14D06A pencil of Enriques surfaces of index one with no sectiontext
