On the crossings number of a hyperplane by a stable random process
Journal Title: Карпатські математичні публікації - Year 2018, Vol 10, Issue 2
Abstract
The numbers of crossings of a hyperplane by discrete approximations for trajectories of an α-stable random process (with 1<α<2) and some processes related to it are investigated. We consider an α-stable process is killed with some intensity on the hyperplane and a pseudo-process that is formed from the α-stable process using its perturbation by a fractional derivative operator with a multiplier like a delta-function on the hyperplane. In each of these cases, the limit distribution of the crossing number of the hyperplane by some discret approximation of the process is related to the distribution of its local time on this hyperplane. Integral equations for characteristic functions of these distributions are constructed. Unique bounded solutions of these equations can be constructed by the method of successive approximations.

Gelfand local Bezout domains are elementary divisor rings
We introduce the Gelfand local rings. In the case of commutative Gelfand local Bezout domains we show that they are an elementary divisor domains.
Pointwise stabilization of the Poisson integral for the diffusion type equations with inertia
In this paper we consider the pointwise stabilization of the Poisson integral for the diffusion type equations with inertia in the case of finite number of parabolic degeneracy groups. We establish necessary and sufficie...
First Reformulated Zagreb Indices of Some Classes of Graphs
A topological index of a graph is a parameter related to the graph; it does not depend on labeling or pictorial representation of the graph. Graph operations plays a vital role to analyze the structure and properties of...
Metric on the spectrum of the algebra of entire symmetric functions of bounded type on the complex $L_\infty$
It is known that every complex-valued homomorphism of the Fr\'{e}chet algebra $H_{bs}(L_\infty)$ of all entire symmetric functions of bounded type on the complex Banach space $L_\infty$ is a point-evaluation functional...
