A pencil of Enriques surfaces of index one with no section

Jason Michael Starr

Vol. 3 (2009), No. 6, 637–652
Abstract

Monodromy arguments and deformation-and-specialization are used to prove existence of a pencil of Enriques surfaces with no section and index 1. The same technique “completes” the strategy from Graber et al. (2005) proving that the family of witness curves for dimension d depends on the integer d.
