Abstract
Let H=−Δ+x^{2} be the harmonic oscillator on R^{n}. In this paper, we prove estimates on Besov spaces associated to the operator H and the endpoint maximal regularity estimates for the fractional harmonic oscillator H^{α}, 0<α≤1, on the Besov spaces associated to the harmonic oscillator H. These spaces are the appropriate function spaces for the study of estimates on Besov type spaces and the endpoint maximal regularity estimates for the fractional power H^{α} in the sense that similar estimates might fail with the classical Besov spaces.
