The Norwegian Academy of Science and Letters has awarded the Abel prize for the yr 2022 to American Mathematician Dennis Parnell Sullivan, who’s 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 quotation 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 discipline of arithmetic which was born within the nineteenth century and has to do with properties of surfaces that don’t change when they’re deformed. Topologically, a circle and a sq. are the identical; equally, surfaces of a doughnut and a espresso mug with one deal with are topologically equal, nonetheless the floor of a sphere and a espresso mug are usually not equal.

Early influences

This mapping was what excited Dennis P. Sullivan when he was within the second yr of a Chemical Engineering course at Rice University, Texas. “The epiphany for me was watching the professor explaining that any surface topologically like a balloon, and no matter what shape – a banana or the statue of David by Michelangelo could be placed on to a perfectly round sphere so that the stretching or squeezing. required at each and every point is the same in all directions at each such point,” he stated. Further the correspondence was distinctive as soon as the situation of three factors was specified and these factors might be specified arbitrarily… “This was general , deep and absolutely beautiful,” he recollects. He without delay modified his main to take up arithmetic, which turned his lifelong curiosity.

He was so struck by this idea that he used it in later analysis, particularly throughout a 10-year wrestle with a proving mathematically, by 1990, a numerical Universality found by physicists within the mid-Nineteen Seventies.

Changing the panorama, constructing 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 launch given by the Academy.

The launch additional says that Prof. Sullivan has discovered deep connections between quite a lot of areas of arithmetic. One of his key breakthroughs is in growing a brand new means of understanding rational homotopy principle, a subfield of algebraic topology. Later, within the late Nineteen Seventies, he began engaged on dynamical techniques, a discipline thought of far faraway from algebraic topology. Dynamical techniques is the examine of a degree transferring in geometrical house.

In 1999, he and his spouse and collaborator, Moira Chas, found a brand new invariant for a manifold based mostly on loops, creating the sphere of string topology.

Dennis P. Sullivan has received quite a few awards, amongst them the Steele Prize, the 2010 Wolf Prize in Mathematics and the 2014 Balzan Prize for Mathematics. He can be a fellow of the American Mathematical Society.
