The defect formula

E Nart, J Novacoski - Advances in Mathematics, 2023 - Elsevier
In this paper we present a characterization for the defect of simple algebraic extensions of
valued fields. This characterization generalizes the known result for the henselian case …

K\" ahler differentials of extensions of valuation rings and deeply ramified fields

SD Cutkosky, FV Kuhlmann - arXiv preprint arXiv:2306.04967, 2023 - arxiv.org
Assume that $(L, v) $ is a finite Galois extension of a valued field $(K, v) $. We give an
explicit construction of the valuation ring $\cO_L $ of $ L $ as an $\cO_K $-algebra, and an …

Parametrizations of subsets of the space of valuations

J Novacoski, CH Silva de Souza - Mathematische Zeitschrift, 2024 - Springer
In this paper we present different ways to parametrize subsets of the space of valuations on
K [x] extending a given valuation on K. We discuss the methods using pseudo-Cauchy …

On the computation of K\" ahler differentials and characterizations of Galois extensions with independent defect

SD Cutkosky, FV Kuhlmann, A Rzepka - arXiv preprint arXiv:2305.10022, 2023 - arxiv.org
For important cases of algebraic extensions of valued fields, we develop presentations of the
associated K\" ahler differentials of the extensions of their valuation rings. We compute their …
