Some remarks on the generalized Hertling conjecture for Tjurina spectrum

Algebraic Geometry 2026-05-29 v9

Abstract

We study the original version of the generalized Hertling conjecture on the variance of the Tjurina spectral numbers, which was proposed by Shi, Wang, and Zuo, and provide a sufficient condition for the original conjecture to fail, employing a theorem of Hertling in an essential way. We calculate certain examples using some codes in Singular.
