On the D-module of an isolated singularity
Thomas Bitoun
Let Z be the germ of a complex hypersurface isolated singularity of equation f, with Z at least of dimension 2. We consider the family of analytic D-modules generated by the powers…
Extending meromorphic connections to coadmissible D-cap-modules
Thomas Bitoun, Andreas Bode
We investigate when a meromorphic connection on a smooth rigid analytic variety gives rise to a coadmissible -cap-module, and show that this is always the case w…
Length of local cohomology in positive characteristic and ordinarity
Thomas Bitoun
Let be the ring of Grothendieck differential operators of the ring of polynomials in variables with coefficients in a perfect field of positive characteristic …
On D-modules related to the b-function and Hamiltonian flow
Thomas Bitoun, Travis Schedler
Let f be a quasi-homogeneous polynomial with an isolated singularity. We compute the length of the D-modules generated by complex powers of f in terms of the Hodge…
On a theory of the -function in positive characteristic
Thomas Bitoun
We present a theory of the -function (or Bernstein-Sato polynomial) in positive characteristic. Let be a non-constant polynomial with coefficients in a perfect field of…
On the -supports of a holonomic -module
Thomas Bitoun
For a smooth variety over a perfect field of positive characteristic, the sheaf of crystalline differential operators on (also called the sheaf of -differential o…
