The (logarithmic) Sobolev inequalities along geometric flow and applications (1502.02305v3)

Abstract: For some class of geometric flows, we obtain the (logarithmic) Sobolev inequalities and their equivalence up to different factors directly and also obtain the long time non-collapsing and non-inflated properties, which generalize the results in the case of Ricci flow or List-Ricci flow or harmonic-Ricci flow. As applications, for mean curvature flow in Lorentzian space with nonnegative sectional curvature and twisted K\"ahler-Ricci flow on Fano manifolds, we get the results above.
