Motivic apsects of a remarkable class of Calabi-Yau threefolds
Gregory Pearlstein, Chris Peters
In this note we consider the motivic aspect of the middle cohomology of more than 200 classes of quasi-smooth Calabi--Yau threefolds inside weighted projective 4-space which come w…
On isolated hypersurface singularities: algebra-geometric and symplectic aspects
Chris Peters
These notes are based on a seminar which took place in the autumn of 2022 at the Mathematical Institute of the University of Leiden. Its goal was to understand the recent work of J…
A note on the primitive cohomology lattice of a projective surface
Chris Peters
The isometry class of the intersection form of a compact complex surface can be easily determined from complex-analytic invariants. For projective surfaces the primitive lattice is…
Holomorphic Bisectional Curvature and Applications to Deformations and Rigidity for Variations of Mixed Hodge Structure
Gregory Pearlstein, Chris Peters
In this article, we prove a rigidity criterion for period maps of admissible variations of graded-polarizable mixed Hodge structure, and establish rigidity in a number of cases, in…
