Here, we propose a method to obtain local analytic approximate solutions of ordinary differential equations with variable coefficients, or even some nonlinear equations, inspired in the Lyapunov method, where instead of p

In this contribution to the study of one-dimensional point potentials, we prove that if we take the limit $q\to 0$ on a potential of the type ${v}_{0}\delta (y)+2{v}_{1}{\delta }^{\prime }(y)+{w}_{0}\delta (y-q)+2{w}_{1}{\delta }^{\prime }(y-q),$ we
