| Research Abstract |
I have studied various problems in gauge theory, which especially possesses the sypersymmetry, by using perturbative/non-perturbative methods and superstring theory. I have investigated mainly the following 6 themes in the period of my research project:
(1) Matrix regularization of 3 dimensional Chern-Simons theory and 2 dimensional BF theory and Localization
(2) Solitons in supersymmetric gauge theory and tropical geometry
(3) Understanding of spontaneous supersymmetry breaking via brane configurations in superstring theory
(4) Analysis of duality cascades in supersymmetric gauge theories by the renormalization group flow
(5) Novel mechanism of the gauge field localization on the domain-walls
(6) Evaluation of the volume of the moduli space of BPS vortices by the localization method
