For a linear ordinary differential equation of variable coefficients in which the highest order derivative $d^{n}y/dx^n$ is multiplied by a small parameter $\epsilon ...
Scientists have uncovered a breakthrough in our understanding of black holes by using a powerful mathematical tool known as the exact Wentzel-Kramers-Brillouin (WKB) method. The study, published in ...
Building on ES_APPM 420-1, this course covers advanced perturbation and asymptotic methods. They may include methods for ordinary differential equations (e.g. WKB method), for integrals (e.g.
