Alexander Ritter

Alexander Ritter is a Research Fellow at the Mathematical Institute, University of Oxford, within the Department of Mathematics. His research focuses on symplectic topology, Homological Mirror Symmetry, Floer theory, and Gromov-Witten theory. He has contributed to significant publications on quantum cohomology and Floer invariants, including joint works with Filip Živanović and Mark McLean. Ritter has held academic positions at Stanford University and has been affiliated with Trinity College, Cambridge, where he received several scholarships and prizes. He teaches a range of undergraduate and graduate courses in mathematics, including topics in algebraic topology, analysis, and geometry.

Alexander F. Ritter is a Professor of Mathematics at the University of Oxford, specializing in Symplectic Topology. His research focuses on the interplay between symplectic geometry and algebraic structures, particularly through the lens of Floer theory and quantum cohomology. He investigates topics such as symplectic cohomology, exact Lagrangian embeddings, and the open-closed string map. His work often involves the study of symplectic manifolds with circle actions, Fano toric varieties, and ALE spaces. Ritter's contributions highlight the connections between symplectic topology and algebraic geometry, especially through the McKay correspondence and Gromov-Witten invariants.
