Several complex variables are better than just one

In this popular expository article, we discuss some important ways in which complex analysis in more than one variable is different from complex analysis in one variable. Analytic continuation in several variables is contrasted with that in one variable, and the notion of psuedoconvexity is defined. Hartogs phenomenon and the Levi problem are also discussed in an informal way.     

M K Chandrashekaran (1937–2009)

Maroli Krishnayya Chandrashekaran, Editor of Journal of Biosciences (from 1991 to 1997) and Resonance (from 2003 to 2005), was a biologist who stood out from his peers as much on account of the quality of his contributions as because of his style. He made major contributions to our understanding of the interplay between time and the living world (which also became the title of a book he wrote). This article aims to bring together aspects of his life and work.
