چکیده

Dimension-independent Harnack inequalities are derived for a class of subordinate semigroups. In particular, for a diffusion satisfying the BakryEmery curvature condition, the subordinate semigroup with power α satisfies a dimension-free Harnack inequality provided α ∈ ` 1 2 , 1 ́ , and it satisfies the log-Harnack inequality for all α ∈ (0, 1). Some infinite-dimensional examples are also presented.

To appear in Potential Analysis. DIMENSION-INDEPENDENT HARNACK INEQUALITIES FOR SUBORDINATED SEMIGROUPS

Super Poincaré and Nash-type inequalities for Subordinated Semigroups

We prove that if a super-Poincaré inequality is satisfied by an infinitesimal generator −A of a symmetric contraction semigroup on L2 and that is contracting on L1, then it implies a corresponding super-Poincaré inequality for −g(A) for any Bernstein function g. We also study the converse of this statement. We prove similar results for Nash-type inequalities. We apply our results to Euclidean, ...

Se p 20 09 Harnack Inequality and Applications for Stochastic Evolution Equations with Monotone Drifts ∗

As a Generalization to [37] where the dimension-free Harnack inequality was established for stochastic porous media equations, this paper presents analogous results for a large class of stochastic evolution equations with general monotone drifts. Some ergodicity, compactness and contractivity properties are established for the associated transition semigroups. Moreover, the exponential converge...

Singular Stochastic Equations on Hilbert Spaces: Harnack Inequalities for their Transition Semigroups

We consider stochastic equations in Hilbert spaces with singular drift in the framework of [7]. We prove a Harnack inequality (in the sense of [18]) for its transition semigroup and exploit its consequences. Supported in part by “Equazioni di Kolmogorov” from the Italian “Ministero della Ricerca Scientifica e Tecnologica” Supported by the DFG through SFB-701 and IRTG 1132, by nsf-grant 0603742 ...

Global Positivity Estimates and Harnack Inequalities for the Fast Diffusion Equation

We investigate local and global properties of positive solutions to the fast diffusion equation ut = ∆u m in the range (d− 2)+/d < m < 1, corresponding to general nonnegative initial data. For the Cauchy problem posed in the whole Euclidean space R we prove sharp Local Positivity Estimates (Weak Harnack Inequalities) and Elliptic Harnack inequalities; we use them to derive sharp Global Positivi...
