Twisted Gelfand-Ponomarev modules

Joseph Muller, Chia-Fu Yu

In this expository paper, given a field $K$ and two automorphisms $I ¨ , I ¨ \in Aut (K)$ , we give a self-contained proof of the classification of finite dimensional $K$ -vector…

Introduction to DieudonnÃ© modules and supersingular abelian varieties revisited

Chia-Fu Yu

In this Note we present an expository account for \dieu modules and revisit supersingular abelian varieties. We give a simple proof of the uniqueness of products of two or more sup…

Polarized superspecial abelian varieties over $F_{p}$ via hermitian lattices

Yucui Lin, Jiangwei Xue, Chia-Fu Yu

We study the set of isomorphism classes of polarized superspecial abelian varieties $(A, I^»)$ of a fixed dimension over $F_{p}$ with Frobenius endomorphism $I ¨ _{A} = - p$ a…
