| Research Abstract |
Minimal representations are building blocks of unitary representations. During this period, we established the Schrodinger model of minimal representations of the indefinite orthogonal group, and determined a closed formula of the unitary inversion operator on the L^2-model on the isotropic cones, that generalizes the Euclidean Fourier transform. A new deformation theory was introduced in [1]. Further, I made systematic and synthetic applications of the original theory of visible actions on complex manifolds to multiplicity-free theorems, in particular, branching problems to symmetric pairs.
