Overview of your research

I am interested in the harmonic analysis on solvable Lie groups and on their compact extensions. Most interest objects are Gelfand pairs and the corresponding homogeneous spaces. In order to analyze them, I study spherical representations and spherical functions. The constructions of spherical representations for Gelfand pairs and calculations of invariant differential operators for multiplicity-free actions are very useful for the investigations of them.
