The Hasse norm principle for $A_{4}$ -quartic extensions of global function fields

Anand Deopurkar, Rachel Newton, Vaidehee Thatte +1

For a finite extension of global fields $K / k$ , the norm map $N_{K / k} : K^{\times} \to k^{\times}$ extends to a map on idèle groups. The Hasse norm principle holds if every element of $…

Upper Ramification Groups for Arbitrary Valuation Rings

Kazuya Kato, Vaidehee Thatte

T. Saito established a ramification theory for ring extensions locally of complete intersection. We show that for a Henselian valuation ring $A$ with field of fractions $K$ and for…

Ramification theory for degree $p$ extensions of arbitrary valuation rings in mixed characteristic $(0, p)$

Vaidehee Thatte

We previously obtained a generalization and refinement of results about the ramification theory of Artin-Schreier extensions of discretely valued fields in characteristic $p$ with…

Ramification Theory for Artin-Schreier Extensions of Valuation Rings

Vaidehee Thatte

The goal of this paper is to generalize and refine the classical ramification theory of complete discrete valuation rings to more general valuation rings, in the case of Artin-Schr…
