Inverse Cauchy problem for fractional telegraph equations with distributions
Journal Title: Карпатські математичні публікації - Year 2016, Vol 8, Issue 1
Abstract
The inverse Cauchy problem for the fractional telegraph equation $$u^{(\alpha)}_t-r(t)u^{(\beta)}_t+a^2(-\Delta)^{\gamma/2} u=F_0(x)g(t),\quad (x,t) \in {\rm R}^n\times (0,T],$$ with given distributions in the right-hand sides of the equation and initial conditions is studied. Our task is to determinate a pair of functions: a generalized solution $u$ (continuous in time variable in general sense) and unknown continuous minor coefficient $r(t)$. The unique solvability of the problem is established.

Application of the spectral theory and perturbation theory to the study of Ornstein-Uhlenbeck processes
The theoretical bases of this paper are the theory of spectral analysis and the theory of singular and regular perturbations. We obtain an approximate price of Ornstein-Uhlenbeck double barrier options with multidimensio...
On the multiplicative order of elements in Wiedemann's towers of finite fields
We consider recursive binary finite field extensions Ei+1=Ei(xi+1), i≥−1, defined by D. Wiedemann. The main object of the paper is to give some proper divisors of the Fermat numbers Ni that are not equal to the multiplic...
Skew semi-invariant submanifolds of generalized quasi-Sasakian manifolds
In the present paper, we study a new class of submanifolds of a generalized Quasi-Sasakian manifold, called skew semi-invariant submanifold. We obtain integrability conditions of the distributions on a skew semi-invaria...
The limiting oscillations of continuous functions
We prove that for any upper semicontinuous function f:F→[0;+∞] defined on the boundary F=¯¯¯¯G∖G of some open set G in metrizable space X there is a continuous function g:G→R such that the limiting oscillation ˜ωg of it...
Properties of distance spaces with power triangle inequalities
Metric spaces provide a framework for analysis and have several very useful properties. Many of these properties follow in part from the triangle inequality. However, there are several applications in which the triangle...
