We prove a precise version of a general conjecture on the polar degree stated by June Huh. We confirm Huh's conjectural list of all projective hypersurfaces with isolated singularities and polar degree equal to 2.

Degeneration of the Leray Spectral Sequence for Certain Geometric Quotients
Autor: Chris Peters, J. H. M. Steenbrink
Publikováno v: Moscow Mathematical Journal. 3:1085-1095
We prove that the Leray spectral sequence in rational co- homology for the quotient map Un;d! Un;d=G where Un;d is the ane variety of equations for smooth hypersurfaces of degree d in P n (C) and G is the general linear group, degenerates at E2. 2000

[Untitled]
Autor: Chris Peters, J. H. M. Steenbrink
Publikováno v: Acta Applicandae Mathematicae. 75:183-194
We present a survey of the properties of the monodromy of local systems on quasi-projective varieties which underlie a variation of Hodge structure. In the last section, a less widely known version of a Noether–Lefschetz-type theorem is discussed.

Motivic Milnor Fibre for Nondegenerate Function Germs on Toric Singularities
Autor: J. H. M. Steenbrink
Publikováno v: Bridging Algebra, Geometry, and Topology ISBN: 9783319091853
We study function germs on toric varieties which are nondegenerate for their Newton diagram. We express their motivic Milnor fibre in terms of their Newton diagram. We extend a formula for the motivic nearby fibre to the case of a toroidal degenerati

The configuration of bitangents of the Klein curve

The configuration of bitangents of a smooth quartic curve in P2(C) has been a classical object of study. In particular for the Klein curve xy3 + yz3 + zx3 = 0 it is highly symmetric (Baker 1935; Klein 1879). Key concepts are Steiner sets and Aronhold

Quartic Double Solids with Ordinary Singularities
Autor: M. I. Grooten, J. H. M. Steenbrink
Publikováno v: Proceedings of the Steklov Institute of Mathematics, 267, pp. 104-112
Proceedings of the Steklov Institute of Mathematics, 267, 104-112
We study the mixed Hodge structure on the third homology group of a threefold which is the double cover of projective three-space ramified over a quartic surface with a double conic. We deal with the Torelli problem for such threefolds.

Hodge Number Polynomials for Nearby and Vanishing Cohomology
Autor: J. H. M. Steenbrink, Chris Peters
We recall the construction of the Hodge character and we show, us-ing a result due to F. Bittner, that these can be constructed usingclassical pure Hodge theory only, sideskipping Deligne’s constructionof functorial mixed Hodge structures on the co
