Strong law of large number of a class of super-diffusions.
Complexity of Non-Adaptive Optimization Algorithms for a Class of Diffusions
Global optimization average-case complexity diffusion processes
2015/7/8
This paper is concerned with the analysis of the average error in approximating the global minimum of a 1-dimensional, time-homogeneous diffusion by non-adaptive methods. We derive the limiting distri...
Markov chain Monte Carlo for exact inference for diffusions
Exact inference Exact simulation Markov chain Monte Carlo Stochastic differential equa-tion Transition density
2011/3/25
We develop exact Markov chain Monte Carlo methods for discretely-sampled, directly and indirectly observed diffusions. The qualification "exact" refers to the fact that the invariant and limiting dist...

2010/10/19
It has recently been shown that there are grave differences in the regularity behavior of the empirical process based on scalar diffusions as compared to the classical empirical process, due to the e...

2010/3/10
We study the problem of estimating parameters of the limiting equation
of a multiscale diffusion in the case of averaging and homogenization, given
data from the corresponding multiscale system. Fir...

The existence of the effective diffusivity tensor for diffusions with incompressible mixing drifts
Random field diffusions in random media mixing
2009/9/21
In the present article we consider a model of motion of
a passive tracer particle under a random, non-steady (time dependent),
incompressible velocity flow in a medium with positive molecular diffus...

Random field diffusions in random media Lagrangian process
2009/9/21
We study the equation of a motion of a passivc tracer
in a time-independent turbulent flow in a medium with a positive
molecular diffusivity. In [6] the authors have shown the existence of
an invar...
Branching diffusions, superdiffusions and random media
spatial branching processes branching diffusions measure-valued processes superprocesses catalytic branching Law of Large Numbers
2009/5/18
Spatial branching processes became increasingly popular in the past decades, not only because of their obvious connection to biology, but also because superprocesses are intimately related to nonlinea...

We study the dynamical properties of the Brownian diffusions having σ Id as diffusion coefficient matrix and b=∇U as drift vector. We characterize this class through the equality D+2=D-2, where ...
