Central extensions of divisible groups
… to the classification of central extensions of divisible groups with finite abelian quotient, so called ``d-ab extensions.'' We give a matrix classification of equivalence classes of d-ab extensions and explicitly provide a family of group presentations. We provide a criterion for determining …

On The Orbital Rigidity Conjecture And Sustained P-Divisible Groups
The orbital rigidity phenomenon for p-divisible groups was first discovered by Ching-LiChai, motivated by the Hecke orbit conjecture. Later, the general orbital rigidity conjecture was formulated and the second case of this conjecture was proved by Ching-Li Chai and Frans Oort. In this thesis we …

Transchromatic generalized character maps
… E^*(BG). In this paper we use the geometry of p-divisible groups to describe a sequence of ""intermediate"" character theories that retain more information about the cohomology theory E and yield the related result of Hopkins, Kuhn, and Ravenel as a special case."
