Geometric Function Theory is that part of Complex Analysis which covers the theory of conformal and quasiconformal mappings.

Current and historical research methods in approximation theory are presented in this book beginning with the 1800s and following the evolution of approximation theory via the refinement and extension of classical methods and ending with recent techniques and methodologies.

A broad survey of the theory of rectifiability and its deep connections to numerous different areas of mathematics.

This textbook provides a gentle introduction to intersection homology and perverse sheaves, where concrete examples and geometric applications motivate concepts throughout.
