Srinivasa Ramanujan’s extraordinary contributions to mathematical analysis, number theory, infinite series, and continued fractions are unparalleled. The Infosys-ICTS Ramanujan Lectures are delivered by renowned mathematicians on important developments in their area of speciality. The first lecture in the series is aimed at a general audience while the rest are for mathematicians.

03 November 2015, 16:00 to 17:00
Ramanujan Lecture Hall, ICTS campus
Far from equilibrium behavior is ubiquitous.Indeed most of the processes that characterize energy flow occur far from equilibrium. These range from very large systems, such as weather patterns or ocean currents that remain far from equilibrium owing to an influx of energy, to biological structures...more

Modular forms are holomorphic functions on the upper half plane which have a high degree of symmetry. Galois theory studies permutation symmetries of roots of polynomial equations defined over the rationals. There is a close and occult connection between these two completely different symmetries...more

One of the most studied objects in mathematics is the modular curve, given as the locally symmetric space which is the quotient of 2-dimensional hyperbolic space by congruence subgroups of SL_2(Z). In particular, it is naturally the home of modular forms. It also has an algebraic structure as the...more

Lecture 1: The Generalized Ramanujan Conjectures Abstract: One of the central problems in the modern theory of automorphic forms is the Generalized Ramanujan Conjecture.We review the development and formulation of these conjectures as well as recent progress. While the general Conjecture is not...more
