The names a theorem which states that the integral of a complex-valued function on a closed contour in a simply-connected domain is zero. A generalization of his eponymous integral formula is used to define the coefficients of the terms in a Laurent series. With Bernhard Riemann, he is the namesake of two partial differential equations
