On Noether's Degree Bound for Finite Group Schemes

Commutative Algebra 2025-06-02 v1

Abstract

This paper establishes Noether's classical degree bound β(G)G\beta(G) \le |G| for finite and linearly reductive group schemes. On the other hand, we provide examples of infinitesimal group schemes where β(G)\beta(G) is unbounded. We also generalize Molien's formula to finite and linearly reductive group schemes.
