Logarithmic Sobolev inequalities for fractional diffusion. (English) Zbl 1397.60050
Summary: In this note, logarithmic Sobolev inequalities are established on the path space for the fractional Brownian motion with drift. The reference distance on the path space is the $$L^2$$-norm of the gradient along paths.
