Reyer Sjamaar is a Professor of Mathematics at Cornell University, specializing in differential geometry. His research focuses on symplectic geometry, moment maps, and reduction theory, with an emphasis on singularities and convexity properties. He has contributed significantly to the understanding of symplectic reduction, coadjoint orbits, and the interplay between geometry and representation theory. His work includes the study of stratified symplectic spaces, implosion, and the application of convexity theorems to Hamiltonian group actions. Sjamaar's publications often explore the connections between differential geometry and algebraic structures, particularly in the context of equivariant cohomology and K-theory.
