  • A Criterion for p-Closedness of Derivations in Dimension Two

    Mitsui, K; Sato, N

    INTERNATIONAL MATHEMATICS RESEARCH NOTICES ( International Mathematics Research Notices )  2025 ( 10 )   2025.05 [ Peer Review Accepted ]

    Type of publication: Research paper (scientific journal)

    　View Summary

    Abstract Jacobson developed a counterpart of Galois theory for purely inseparable field extensions in positive characteristic. In his theory, a certain type of derivations replace the role of the generators of Galois groups. This article provides a convenient criterion for determining such derivations in dimension two. We also present examples demonstrating the efficiency of our criterion.
