Rational Approximation for Two-Point Boundary value problems
Paolo Amore, Francisco M. Fernandez
We propose a method for the treatment of two--point boundary value problems given by nonlinear ordinary differential equations. The approach leads to sequences of roots of Hankel d…
Going beyond perturbation theory: Parametric Perturbation Theory
Paolo Amore
We devise a {\sl non--perturbative} method, called {\sl Parametric Perturbation Theory} (PPT), which is alternative to the ordinary perturbation theory. The method relies on a prin…
A new approach to resummation: Parametric Perturbation Theory
Paolo Amore
We present a {\sl non--perturbative} method, called {\sl Parametric Perturbation Theory} (PPT), which is alternative to the ordinary perturbation theory. The method relies on a pri…
A new representation for non--local operators and path integrals
Paolo Amore
We derive an alternative representation for the relativistic non--local kinetic energy operator and we apply it to solve the relativistic Salpeter equation using the variational si…
