Abel prize for 2022 goes to American mathematician Dennis P. Sullivan

The Norwegian Academy of Science and Letters has awarded the Abel prize for the year 2022 to American Mathematician Dennis Parnell Sullivan, who is with the Graduate School and University Center of the City University of New York and the State University of New York at Stony Brook. The citation mentions that the award has been given, “For his groundbreaking contributions to topology in its broadest sense, and in particular its algebraic, geometric and dynamical aspects.” Topology is a field of mathematics which was born in the nineteenth century and has to do with properties of surfaces that do not change when they are deformed. Changing the landscape, building bridges “Dennis P. Sullivan has repeatedly changed the landscape of topology by introducing new concepts, proving landmark theorems, answering old conjectures and formulating new problems that have driven the field forwards,” says Hans Munthe-Kaas, chair of the Abel Committee, in a press release given by the Academy. Dennis P. Sullivan has won numerous awards, among them the Steele Prize, the 2010 Wolf Prize in Mathematics and the 2014 Balzan Prize for Mathematics.
