Alexandre Alexandrovich Kirillov

Alexandre Alexandrovich Kirillov is one of the most influential mathematicians of the twentieth century. His pioneering work on the orbit method — linking coadjoint orbits of Lie groups to unitary representations — transformed the landscape of representation theory and has had profound and lasting impact across geometry, mathematical physics, and algebra. This conference celebrates his 90th birthday and the enduring legacy of his ideas, bringing together leading mathematicians whose work has been shaped by his vision.
