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…

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 $…

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…
