Complex Approximation
Originally, complex approximation was about approximating a holomorphic function, defined on an open subset of the complex plane, by polynomials. Subsequently one was led to consider more general problems: the function to be approximated had several, perhaps infinitely many variables, and the approximating functions could come from classes of functions other than polynomials.
In my talk I will describe one line of research, starting with Carl Runge's discovery from 1885 and leading up to recent results. I will also explain why approximations are in a sense inevitable in complex analysis/geometry.
