Asymptotics In A Complex Plane - Detailed Analysis & Overview
We discuss the digamma-function and its properties. See how to use Saddle Point Approximation to obtain the Here we address the famous Watson's lemma for computation of loop integrals, P1. Week 2: Laplace method and stationary phase approximation. This time we discuss how to use Euler's digamma function to compute highly nontirvial integrals, Part 1. We discuss the Stokes phenomenon using Airy function as an example. The course is for ...
We discuss the so called Hankel representation of the Gamma-function in the We discuss how to compute infinite products using Gamma functions. We discuss definition and elementary properties of Gamma function and also derive a mirror identity. This time we discuss how to use Euler's digamma function to compute highly nontirvial integrals, Part 2. An introduction to the method of solving differential equations with linear coefficients with Laplace contour integral. Part 1. An intuitive introduction to transformations in the
