We prove that the lowest upper bound for the number of isolated zeros of the Abelian integrals associated to quadratic Hamiltonian vector fields having a center and an invariant straight line after ...

In this paper, some simple methods for the calculation of line integrals over smooth curves are considered, where an explicitly differential parametrization for the curve is either not available or is ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations ...
