" Symmetry is one of the thematic melodies oftwentieth-centuryphysics   " It is in these colorful terms that Nobel Prize-winning physicist C.N. Yang highlights the invasion of modern physics by ideas of symmetry, which have played an essential guiding role in its development and continue to play this role with equal vigor.

Lectures at Fields, Strings and Gravity will focus on the study of symmetries that appear in field theory and string theory, with a particular interest in the infinite-dimensional symmetries present in Einstein's theory of gravitation and its generalizations.

They will cover topics as diverse as the description of space-like singularities, asymptotic symmetries that emerge at spatial infinity, and the BRST formulation of gauge theories.
