Prismatic -crystals and Wach modules
Abhinandan
We show that the category of analytic/completed prismatic -crystals on the absolute prismatic site of a small (unramified at ) base ring is naturally equivalent to the catego…

Crystalline representations and Wach modules in the relative case II
Abhinandan
We study relative Wach modules generalising our previous works on this subject. Our main result shows a categorical equivalence between relative Wach modules and lattices inside re…

Crystalline part of the Galois cohomology of crystalline representations
Abhinandan
For and an unramified extension with perfect residue field, we define a syntomic complex with coefficients in a Wach module over a certain period r…

Syntomic complex and -adic nearby cycles
Abhinandan
In local relative -adic Hodge theory, we show that the Galois cohomology of a finite height crystalline representation (up to a twist) is essentially computed via the (Fontaine-…
