K3 surfaces associated to Abelian Fourfolds of Mumford's Type
Yuwei Zhu
Mumford constructed a family of abelian fourfolds with special stucture not characterized by endomorphism ring. Galluzzi showed that the weight 2 Hodge structure of such a variety…

Constructing a CM Mumford fourfold from Shioda's fourfold
Yuwei Zhu
Shioda proved that the Jacobian of the curve is a 4-dimensional CM abelian variety with codimension 2 Hodge cycles not generated by divisors. It was noted by S…
