On the equivalence of Prony and Lanczos methods for Euclidean correlation functions
Johann Ostmeyer, Aniket Sen, Carsten Urbach
We investigate the oblique Lanczos method recently put forward in arXiv:2406.20009 for analysing Euclidean correlators in lattice field theories and show that it is analytically eq…
