 Analytic Continuation Analytic continuation is a way of extending the domain over which a complex function is defined. Analytic Function An analytic function is a complex function that is complex differentiable at every point in a region. Complex Analysis Complex analysis is the study of complex functions and their derivatives, manipulation, and other properties. Conformal Mapping A conformal mapping is a transformation in the complex plane that preserves local angles. Pole In comlpex analysis, a pole is a singularity of a complex function. Riemann Sphere The Riemann sphere is a name given to the complex plane together with a point at infinity, which has the topology of a sphere. Riemann Surface A Riemann surface is a surface that represents the domain of a multiple-valued complex function. Singularity In mathematics, a singularity is a point at which an equation, surface, etc., blows up or becomes degenerate. Singularities are often also called singular points.
