Lanczos-like algorithm for the time-ordered exponential: The -inverse problem
Pierre-Louis Giscard, Stefano Pozza (2020)
Applications of Mathematics
The time-ordered exponential of a time-dependent matrix is defined as the function of that solves the first-order system of coupled linear differential equations with non-constant coefficients encoded in . The authors have recently proposed the first Lanczos-like algorithm capable of evaluating this function. This algorithm relies on inverses of time-dependent functions with respect to a non-commutative convolution-like product, denoted by . Yet, the existence of such inverses, crucial to...
