Roots of Bernstein-Sato polynomials for projective hypersurfaces with ordinary double points

Seung-Jo Jung, Morihiko Saito

Let $X \subset P^{n - 1}$ be a hypersurface of degree $d \geq 3$ with ordinary double points, where $n \geq 3$ . The roots of Bernstein-Sato polynomial of its defining polynomial $f…

Spectrum of cones of projective hypersurfaces with singularities isolated

Seung-Jo Jung, Morihiko Saito, Youngho Yoon

Let $Z$ 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 $f$ , the Steenbrink spectrum can be defined as the Poincaré polynomial of the graded quotients of the $…
