Alexander Givental

Alexander Givental (Александр Борисович Гивенталь[1]) is a Russian American mathematician working in the area of symplectic topology, singularity theory and their relations to topological string theories. He earned his Ph.D. under the supervision of V. I. Arnold, in 1987. He provided the first proof of the mirror conjecture for Calabi–Yau manifolds that are complete intersections in toric ambient spaces, in particular for quintic hypersurfaces in P⁴. He is now Professor of Mathematics at the University of California, Berkeley.
