RESEARCH INTERESTS

Viktor Ginzburg's research interest has been in various areas of global analysis. These areas are symplectic topology and Hamiltonian dynamics, Poisson Lie groups and Poisson manifolds, and Hamiltonian actions of Lie groups.

1. Ginzburg's research in symplectic topology and Hamiltonian dynamics focuses on the existence problem for periodic orbits of certain Hamiltonian systems. Hamiltonian systems without periodic orbits and the systems describing the motion of a charge in a magnetic field are his primary concern.

2. The geometry of Poisson Lie groups and Poisson manifolds is known to be strongly related to both the theory of quantum groups and deformation quantization. Ginzburg is interested in the explicit calculation of certain invariants of Poisson manifolds and the study of momentum mappings for Poisson Lie groups.

3. Applications of cobordism techniques to gain a new understanding of various "classic" and recent results in symplectic geometry is the center of his project undertaken jointly with V. Guillemin (MIT) and Y. Karshon (Hebrew University). The examples of such applications are new proofs of the Duistermaat-Heckman formula, the Jeffrey-Kirwan localization theorem, and the fact that geometric quantization commutes with reduction.
