Some remarks on the generalized Hertling conjecture for Tjurina spectrum
Seung-Jo Jung, In-Kyun Kim, Morihiko Saito +1
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 suffic…

Tjurina spectrum and graded symmetry of missing spectral numbers
Seung-Jo Jung, In-Kyun Kim, Morihiko Saito +1
For a hypersurface isolated singularity defined by a convergent power series , the Steenbrink spectrum can be defined as the Poincaré polynomial of the graded quotients of the…

Spectrum of cones of projective hypersurfaces with singularities isolated
Seung-Jo Jung, Morihiko Saito, Youngho Yoon
Let be a projective hypersurface such that its underlying reduced variety has only isolated singularities. In case its irreducible components have constant multiplicities, for…
