VENUE: Ramanujan Lecture Hall, ICTS, Bengaluru

String theory has come a long way, from its origin in 1970's as a possible model of strong interactions, to the present day where it sheds light not only on the original problem of strong interactions, but also on quantum gravity, black hole physics, hydrodynamics, condensed matter systems and particle physics, besides providing tools to explore new structures in quantum field theory and mathematics.

String theorists from India have played a major role in the development of the subject. The meeting will celebrate the ongoing journey of String theory in the form of exposition and discussion of developments at its frontier. There will be talks by the invited speakers from all around the world covering various frontier areas of string theory.

The talks will broadly cover the following areas:

Black hole physics
Formal developments in String theory
Applications of gauge gravity duality to non-equilibium physics
Supersymmetric quantum field theories
Cosmology
Hydrodynamics
Quantum entanglement
Bose-Fermi dualities and application to condensed matter
Conformal field theory

There will be a special session to felicitate Spenta R. Wadia for his contribution to science and institution-building in India.
