| Research Abstract |
We studied the topology of hyperkahler quotients by tori. We showed that we can take the norm square of the hyperkahler moment map as a Morse function under certain conditions. As a result we derived a formula for the Betti numbers and, under certain conditions, determined the cohomology ring. We also studied geometric quantization of flag manifolds. We constructed the one parameter family of Kahler polarization starting from the standard one and converging to the real polarization coming from the Gelfand-Cetlin integrable system at quantum level.
