ARC DP22: DP220100285;聽Harmonic analysis of Laplacians in curved spaces

I work on special mappings between metric spaces that preserve metric related properties, such as isometries, conformal or quasi-conformal mappings. My setting is usually that of sub-Riemannian metrics on Lie groups. I am also interested in the interaction between group theoretic properties and Laplace-like operators. Lately, I have been considered problems of harmonic analysis also on discrete structures such as trees, seen as metric measure spaces.
