Fractional integral along homogeneous curves in the Heisenberg group

Joonil Kim

Chung-Ang University

Abstract

We obtain the type set for the fractional integral operator along the curve $(t,t^2,\alpha t^3)$ on the three dimensional Heisenberg group when $\alpha\neq\pm 1/6$. The proof is based on the Fourier inversion formula and the angular Littlewood-Paley decompositions in the Heisenberg group in [5].

Keywords: typeset, fractional integral, Heisenberg group, group Fourier trasform
