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 prove a third case of this conjecture.
