Number Theory and Related Topics

This work is a collection of original papers presented at an international colloquium on number theory and related topics held at the Tata Institute of Fundamental Research in Bombay. The papers highlight recent developments in number theory and are dedicated to the memory of Srinivasa Ramanujan, the celebrated Indian mathematician. Topics include Ramanujan's formulas for Eisenstein series, the circle method and the Fourier coefficients of modular forms, linear operators and automorphic forms, exponential Diophantine equations, and others.
