Generalized Gelfand-Yaglom Formula for a Discretized Quantum Mechanic System

Mathematical Physics 2021-12-08 v4 math.MP

Abstract

The Gelfand-Yaglom formula relates the regularized determinant of a differential operator to the solution of an initial value problem. Here we develop a generalized Gelfand-Yaglom formula for a Hamiltonian system with Lagrangian boundary conditions in the discrete and continuous settings. Later we analyze the convergence of the discretized Hamilton-Jacobi operator and propose a lattice regularization for the determinant.
