Order 5 Brauer-Manin obstructions to the integral Hasse principle on log K3 surfaces (2005.14013v1)
Published 28 May 2020 in math.NT and math.AG
Abstract: We construct families of log K3 surfaces and study the arithmetic of their members. We use this to produce explicit surfaces with an order 5 Brauer-Manin obstruction to the integral Hasse principle.
