TITLE:
Flows, currents and symmetries for continuous time Markov chains: a large
deviation approach.
ABSTRACT:
We consider a continuous time Markov chain on a countable space (finite or
…
[View More]infinite).
We focus on the large deviations of the empirical measure, flow and
current, as well as their generalization to higher order. In several cases
the associated rate function is explicit. As application we investigate
the Gallavotti-Cohen functional and its symmetry, and discuss several
systems, including birth-and-death Markov chains, random walks on lattices
approximating diffusions under an external potential, particle systems.

Workshop on computational methods for jump processes.
---------------------------------------------------------------------------
------------

on computational methods for jump processes at Warwick University, UK, from
7th to 9th of July 2014.
The aim of this workshop is to highlight the recent advances in the
estimation and the simulation of jump diffusions. The most recent
achievements in inference of jump diffusions will be considered, such as
series approximation, perfect simulation algorithms, sequential Monte Carlo
methods and spectral based simulation methods.
The plenary speakers are:
Yacine Ait-Sahalia (Princeton University),
Zhiyi Chi (University of Connecticut),
Jean Jacod (Universite Paris VI),
Pierre Del Moral (University of New South Wales),
Arturo Kohatsu-Higa (Ritsumeikan University),
Per Mykland (University of Chicago),
Gareth Roberts (University of Warwick),
Neil Shephard (Harvard University),
Peter Tankov (Universite Paris VII).
Registration and abstract submission for posters and talks is now open until
January 31st 2014. Please find further details on the workshop webpage:
http://www2.warwick.ac.uk/fac/sci/statistics/crism/workshops/jumps/
Note that fundings for junior researchers (a maximum of two years of
experience since completion of Ph.D.) will be available.

Speaker: Pietro Caputo (Universita' di Roma III)
Title: Large deviations in sparse random graphs: a local weak convergence
approach
Abstract:
Consider the Erdos-Renyi random graph on n vertices where each edge is
present …
[View More]independently with probability p = c/n, with c > 0 fixed. For
large n, a typical realization locally behaves like the Galton-Watson
tree with Poisson offspring distribution with mean c. We discuss large
deviations from this typical behavior, within the framework of the
local weak convergence introduced by Benjamini-Schramm and
Aldous-Steele. The associated rate function is expressed in terms of
an entropy functional on unimodular measures and takes finite values
only at measures supported by trees. Along the way, we present a new
configuration model which allows one to sample uniform random graphs
with a given finite neighborhood distribution, provided the latter is
supported by trees. We also present a new class of unimodular random
trees, which generalizes the Galton-Watson tree with given degree
distribution to the case of neighborhoods of arbitrary finite depth.
This is joint work with Charles Bordenave.

BAYESIAN INFERENCE IN TWO-PIECE AND SKEW-SYMMETRIC DISTRIBUTIONS USING JEFFREYS PRIORS
Abstract:
We study the Jeffreys prior and the …
[View More]independence Jeffreys prior of general classes of univariate location-scale two-piece and skew-symmetric models. For the case of two-piece models, Jeffreys priors are shown not to allow for Bayesian inference in the wide and practically relevant class of distributions obtained by skewing scale mixtures of normals. Easily checked conditions under which independence Jeffreys priors can be used for valid inference are derived. In the context of scalar skew-symmetric models, it is shown that the Jeffreys prior of the skewness parameter is symmetric about 0, proper, and with tails O(λ^(−3/2)) under mild regularity conditions. Sufficient conditions for the existence of the posterior distribution induced by the independence Jeffreys prior are investigated for the case when the sampling model belongs to the family of skew-symmetric scale mixtures of normal distributions.
Joint work with Mark F.J. Steel and Brunero Liseo.

Berlin Mathematical School (BMS) - Get Your Math PhD in Berlin
Website: http://www.math-berlin.de/application
The Berlin Mathematical School is the joint graduate school of the mathematics departments at the three major universities in Berlin:
Freie Universität, Humboldt-Universität and Technische Universität.
We offer an excellent (post)graduate program taught in English in a broad and active research environment. This is complemented …
[View More]by our mentoring program, language courses, soft-skills seminars, travel support for summer schools and conferences, and special funding for students with children.
Our seven main research areas are:
* Differential geometry, global analysis and mathematical physics
* Algebraic and arithmetic geometry, number theory
* Probability, statistics and financial mathematics
* Discrete mathematics and combinatorial optimization
* Geometry, topology and visualization
* Numerical mathematics and scientific computing
* Applied analysis and differential equations
The graduate program starts with three to four semesters of course work (Phase I) leading to a master's degree. This is followed by four to six semesters of thesis research (Phase II) leading to a doctoral degree at one of the three universities.
Students who will have completed their bachelor's degree by October 2014 can apply to Phase I; those who will have completed their master's degree by this date can apply to start directly in Phase II.
Complete information about applying to the BMS is available online:
