Its sister journal, the <a href="http://ejp.ejpecp.org/" target="_self">Electronic Journal of Probability</a> (EJP), publishes full-length articles in probability theory. Short papers, those less than 12 pages, should be submitted to ECP first.

Ethier ethier@math.utah.edu Petrov constructed a diffusion process in the Kingman simplex whose unique stationary distribution is the two-parameter Poisson-Dirichlet distribution of Pitman and Yor.  We show that the subset of the simplex comprising vectors whose coordinates sum to 1 is the natural state space for the process.  In fact, the complementary set acts like an entrance boundary. 2014-09-18T23:45:50-07:00 http://ecp.ejpecp.org/article/view/3485 Last zero time or maximum time of the winding number of Brownian motions 2014-09-18T23:46:09-07:00 Izumi Okada okada.i.aa@m.titech.ac.jp In this paper we consider the winding number, $\theta(s)$, of planar Brownian motion and study asymptotic behavior of the process of the maximum time, the time when $\theta(s)$ attains the maximum in the interval $0\le s \le t$. We find the limit law of its logarithm with a suitable normalization factor and the upper growth rate of the maximum time process itself. We also show that the process of the last zero time of $\theta(s)$ in $[0,t]$ has the same law as the maximum time process. 2014-09-18T03:00:23-07:00 http://ecp.ejpecp.org/article/view/3502 Concentration inequalities for Gibbs sampling under $d_{l_{2}}$-metric 2014-09-18T23:46:09-07:00 Neng-Yi Wang wangnengyi@hust.edu.cn The aim of this paper is to investigate the Gibbs sampling that's used for computing the mean of observables with respect to some function $f$ depending on a very small number of variables. For this type of observable, by using the $d_{l_{2}}$-metric one obtains the sharp concentration estimate for the empirical mean, which in particular yields the correct speed in the concentration for $f$ depending on a single observable. 2014-09-18T02:50:33-07:00 http://ecp.ejpecp.org/article/view/3249 A counter example to central limit theorem in Hilbert spaces under a strong mixing condition 2014-09-18T23:46:09-07:00 Davide Giraudo davide.giraudo1@univ-rouen.fr Dalibor Volny Dalibor.Volny@univ-rouen.fr We show that in a separable infinite dimensional Hilbert space, uniform integrability of the square of the norm of normalized partial sums of a strictly stationary sequence, together with a strong mixing condition, does not guarantee the central limit theorem. 2014-08-29T02:43:32-07:00 http://ecp.ejpecp.org/article/view/3025 A connection of the Brascamp-Lieb inequality with Skorokhod embedding 2014-09-18T23:46:09-07:00 Yuu Hariya hariya@math.tohoku.ac.jp We reveal a connection of the Brascamp-Lieb inequality with Skorokhod embedding. Error bounds for the inequality in terms of the variance are also provided. 2014-08-29T02:35:50-07:00
