Base change conductors through intersection theory and quotient singularities
Dennis Eriksson, Lars Halvard Halle, Johannes Nicaise
We perform a systematic study of the base change conductor for Jacobians. Through the lens of intersection theory and Deligne's Riemann-Roch theorem, we present novel computational…

Genus one mirror symmetry for intersection of two cubics in
Dennis Eriksson, Mykola Pochekai
This paper establishes BCOV-type genus one mirror symmetry for the intersections of two cubics in . The proof applies previous constructions of the mirror family by t…

The spectral genus of an isolated hypersurface singularity and a conjecture relating to the Milnor number
Dennis Eriksson, Gerard Freixas i Montplet
In this paper, we introduce the notion of spectral genus of a germ of an isolated hypersurface singularity , defined…
