Study of the Hypergeometric Equation via Data Driven Koopman-EDMD Theory

Axioms, 2023
We consider a data-driven method, which combines Koopman operator theory with Extended Dynamic Mode Decomposition. We apply this method to the hypergeometric equation which is the Fuchsian equation with three regular singular points.
