摘要:For general penalized Markov processes with soft killing, we propose a simple criterion ensuring uniform convergence of conditional distributions in Wasserstein distance to a unique quasi-stationary distribution. We give several examples of application where our criterion can be checked, including Bernoulli convolutions and piecewise deterministic Markov processes of the form of switched dynamical systems, for which convergence in total variation is not possible.

摘要:In this paper, we study the critical level-set of Gaussian free field (GFF) on the metric graph Z(d), d > 6. We prove that the one-arm probability (i.e. the probability of the event that the origin is connected to the boundary of the box B(N)) is proportional to N-2, where B(N) is centered at the origin and has side length 2 left perpendicular N right perpendicular. Our proof is highly inspired by Kozma and Nachmias (J Am Math Soc 24(2):375-409, 2011) which proves the analogous result for the ...

摘要:We study Glauber dynamics for the low temperature (2 +1)D Solid-On-Solid model on a box of side-length n with a floor at height 0 (inducing entropic repulsion) and a competing bulk external field lambda pointing down (the prewetting problem). In 1996, Cesi and Martinelli showed that if the inverse-temperature beta is large enough, then along a decreasing sequence of critical points (lambda((k)K beta)(c)(k=0) the dynamics is torpid: its inverse spectral gap is O(1) when lambda is an element of ...

摘要:We introduce a theory of non-commutative L-p spaces suitable for non-commutative probability in a non-tracial setting and use it to develop stochastic analysis of Grassmann-valued processes, including martingale inequalities, stochastic integrals with respect to Ito-Grassmann processes, Girsanov's formula and a weak formulation of Grassmann SDEs. We apply this new setting to the construction of several unbounded random variables including a Grassmann analog of the Phi(2)(4) Euclidean QFT in a ...
