Transcendental lattices of some K 3‐surfaces

Abstract

AbstractIn a previous paper, [12], we described six families of K 3‐surfaces (over ℂ) with Picard‐number 19, and we identified surfaces with Picard‐number 20. In these notes we classify some of the surfaces by computing their transcendental lattices. Moreover, we show that the surfaces with Picard‐number 19 are birational to a Kummer surface which is the quotient of a non‐product type abelian surface by an involution.
