The Schrödinger equation with piercings
Paolo Amore
We show that the spectrum of the Schrödinger equation in two or higher dimensions does not change when Dirichlet boundary conditions are enforced on a number of isolated points ins…

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 variational sinc collocation method for strong-coupling problems
Paolo Amore
We have devised a variational sinc collocation method (VSCM) which can be used to obtain accurate numerical solutions to many strong-coupling problems. Sinc functions with an optim…
