Polyakov-Alvarez type comparison formulas for determinants of Laplacians on Riemann surfaces with conical singularities

Victor Kalvin

Abstract: We prove Polyakov-Alvarez type comparison formulas for the determinants of Friederichs extensions of Laplacians corresponding to conformally equivalent conical metrics on compact Riemann surfaces. We illustrate our results by obtaining new and recovering known explicit formulas for determinants of Laplacians on surfaces with conical singularities.

“…We believe that this explicit formula for the determinant will allow us to evaluate the determinant of Laplacian on the smooth and singular surfaces obtained by cutting and gluing genus zero constant curvature surfaces with three conical singularities. For some results in this direction see [22,23,25,26,27]. The results can also be of interest in various areas of theoretical physics.…”
