The Calculation of the Topological Degree by Quadrature
Toby C. O’Neil, James W. Thomas · SIAM Journal on Numerical Analysis · 1975
The topological degree of a function on $R^n $, a useful tool in applied mathematics, is computed by applying Gauss–Legendre quadrature to Kronecker’s integral definition. An error analysis is developed from the Sarma–Eberlein measure of goodness.
