US mathematician Dennis Sullivan has won the 2024 Abel Prize for his significant contributions to topology and related fields. Sullivan’s work has advanced the study of shapes and developed tools that have helped solve many mathematical problems. His innovative approach to topology has repeatedly changed the field, introducing new concepts, proving landmark theorems, answering old conjectures, and formulating new problems. The prize, worth 7.5 million Norwegian Kroner (US$854,000), is seen as a lifetime achievement award in mathematics. Sullivan’s work has had a profound impact on the study of manifolds, breaking down the problem into one that could be solved with algebra calculations.
