Panagiota Daskalopoulos of Columbia University and Nataša Šešum of Rutgers University will receive the 2023 Ruth Lyttle Satter Prize for groundbreaking work in the study of ancient solutions to geometric evolution equations.   Ancient solutions are crucial to the understanding of singularities of geometric flows and are of major interest in the theory of renormalization group flows in theoretical physics. Daskalopoulos and Šešum launched a systematic investigation of ancient solutions in 2010 in foundational work with Richard Hamilton. Their deep and influential work over the past decade culminated in the exciting breakthroughs for which this prize is being awarded.
