The programme will have an emphasis on the many recent exciting breakthroughs in the ergodic theory of group actions on homogeneous spaces. This subject, which also goes by the name "homogeneous dynamics" has seen dramatic advances in the last few decades. Homogeneous dynamics comprises the study of group actions on homogeneous spaces of Lie groups. The dynamics of these actions are extremely rich and have surprising connections to diverse parts of mathematics. An early example of such a connection is Margulis's proof of the long standing conjecture of Oppenheim regarding values taken by quadratic forms at integer points. The programme will feature mini courses as well as research level talks exploring recent advances in homogeneous dynamics and their connections to number theory and geometry. India has a strong tradition in this area and the programme will provide an occasion to celebrate the fundamental contributions of S. G. Dani, a pioneer in the subject who turns 75 this year. Young mathematicians, especially those with an interest in these areas are encouraged to apply.
