Gradual smoothing: strong hypercontractivity and logarithmic Sobolev inequalities
Lévy-type operators with kernels comparable to log(I-Δ) produce strong hypercontractivity and eventual boundedness with differentiability gains, but not supercontractivity, while more singular kernels smooth instantly and less singular ones do not regularize.
