Functional determinants for the second variation
arXiv:2212.13455
Abstract
We study the determinant of the second variation of an optimal control problem for general boundary conditions. Generically, this operators are not trace class and the determinant is defined as a principal value limit. We provide a formula to compute this determinant in terms of the linearisation of the extremal flow. We illustrate the procedure in some special cases, proving some Hill-type formulas.
