Hecke operators on differential modular forms mod p
A. Buium, A. Saha
A description is given of all primitive differential series mod p of order 1 which are eigenvectors of all the Hecke operators and which are differential Fourier expansions of diff…
The ring of differential Fourier expansions
A. Buium, A. Saha
For a fixed prime we prove structure theorems for the kernel and the image of the map that attaches to any differential modular function its differential Fourier expansion. The ima…
Differential overconvergence
A. Buium, A. Saha
We prove that some of the basic differential functions appearing in the (unramified) theory of arithmetic differential equations, especially some of the basic differential modular…
p-jets Of p-isogenies
Alexandru Buium
p-jets of finite flat maps of schemes are generally neither finite nor flat. This phenomenon can be seen already in the case of p-isogenies of group schemes. However, for p-divisib…
