On an infinitesimal Polyakov formula for genus zero polyhedra

Alexey Kokotov, Dmitrii Korikov

Let be a genus zero compact polyhedral surface (the Riemann sphere equipped with a flat conical metric ). We derive the variational formulas for the determinant of the Lapla…

On perturbations of the DN map of a disk causing changes of surface topology

Dmitrii Korikov

We establish the degeneration of the Schottky double of a genus 1 Riemann surface with boundary as its DN map tends to the DN map of the unit disk.

Laplacians in spinor bundles over translation surfaces: self-adjoint extentions and regularized determinants

Alexey Kokotov, Dmitrii Korikov

We study the regularized determinants of various self-adjoint extensions of symmetric Laplacians acting in spinor bundles over compact Riemann surfaces with flat s…
