TIM PERUTZ THESIS

Symplectic topology Symplectic manifolds arise both from mathematical physics as phase-spaces for hamiltonian systems and from algebraic geometry as smooth quasi-projective varieties over the complex numbers. Hansol Hong obtained his Ph. Justin Hilburn obtained his Ph. You have partial access to this content. The second aspect concerns symplectic geometry, particularly symplectic Floer homology. I was impressed with the results; here’s a sample: Emily Clader, “Inverse limits of finite topological spaces.

The projects I proposed were rather sophisticated for undergraduate work. Pseudo-holomorphic curve techniques The tangent spaces of a symplectic manifold can be made into complex vector spaces this involves a choice J for how i will act on tangent vectors, but the choice is in some ways inessential. I was impressed with the results; here’s a sample: Dingxin Zhang obtained his Ph. I was assisted by Thomas Peters; without him, the projects would probably not have been a success. Part I—the present paper—is devoted to the symplectic geometry of these Lagrangians. Download Email Please enter a valid email address.

Zack Sylvan obtained his Ph. The second aspect concerns symplectic geometry, particularly symplectic Floer homology. In recent years, symplectic topologists have increasingly come to appreciate an insight from homological algebra, something that was long understood by algebraic geometers studying coherent sheaves on algebraic varieties.

The projects I proposed were rather sophisticated for tehsis work. More precisely, we formulate the notion of core homological mirror symmetrywhich asks for an equivalence between some full subcategory A of F X and some full subcategory B of DCoh Ywhere the inclusion of B into DCoh Y is a derived Morita invariance. Floer homology and cohomology, symplectic aspects 57R I hope soon to complement it with a lay-person’s account.

The REU has continued since Dmitry spent a year as a postdoc at Uppsala University before joining the collaboration in as a visiting assistant professor at UC Berkeley. They fit into a field theory which assigns Floer homology groups to three-manifolds fibred over S 1.
