Asymptotic relation for the density of a multidimensional random evolution with rare poisson switchings
In the Euclidean space $\mathbb{R}^m,\quad m \geq 2,$ the symmetric random evolution $\textbf{X}(t) = (X_1(t),...,X_m(t))$ controlled by a homogeneous Poisson process with parameter $\lambda > 0$ is considered. An asymptotic formula for the transition density $p(\textbf{x},t),\quad t >...

$\textbf{X}(t) = (X_1(t),...,X_m(t))$ controlled by a homogeneous Poisson process with parameter $\lambda > 0$ is considered.
An asymptotic formula for the transition density $p(\textbf{x},t),\quad t > 0,$ of the process $\textbf{X}(t)$ for $\lambda \rightarrow 0$ is obtained.
The behavior of $p(\textbf{x},t)$ near the boundary of the diffusion area in spaces of various dimensions is described. |
