The extraction and immunoassay of fecal steroids is an increasingly common technique, used in both captive and field studies to provide an approximation of an animal's circulating concentration ofâ€¦ (More)

Let k be a perfect field of characteristic p â‰¥ 3. Let X be a non-supersingular K3 surface over k, and Î¨ the enlarged formal Brauer group associated to X. We consider the deformation space of X. Inâ€¦ (More)

We study the variation of unit roots of the Dwork families of Calabi-Yau varieties over a finite field by the method of Dwork-Katz and also from the point of view of formal group laws. A p-adicâ€¦ (More)

We investigate the structures of Calabi-Yau differential equations and the relations to the arithmetic of the pencils of Calabi-Yau varieties behind the equations. This provides explanations of someâ€¦ (More)
