Application of the spectral theory and perturbation theory to the study of Ornstein-Uhlenbeck processes
Journal Title: Карпатські математичні публікації - Year 2018, Vol 10, Issue 2
Abstract
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 multidimensional stochastic diffusion as expansion in eigenfunctions using infinitesimal generators of an (l+r+1) dimensional diffusion in Hilbert spaces. The theorem of closeness estimates of approximate prices is established. We also obtain explicit formulas for derivatives price approximation based on the expansion in eigenfunctions and eigenvalues of self-adjoint operators using boundary value problems for singular and regular perturbations.

Family of wavelet functions on the Galois function base
We construct a family of wavelet systems on the Galois function base. We research and prove properties of systems of the built family.
Continuous block-symmetric polynomials of degree at most two on the space $(L_\infty)^2$
We introduce block-symmetric polynomials on $(L_\infty)^2$ and prove that every continuous block-symmetric polynomial of degree at most two on $(L_\infty)^2$ can be uniquely represented by some "elementary" block-symmetr...
On central automorphisms of crossed modules
A crossed module (T,G,∂) consist of a group homomorphism ∂:T→G together with an action (g,t)→gt of G on T satisfying ∂(gt)=g∂(t)g−1 and ∂(s)t=sts−1, for all g∈G and s,t∈T. The term crossed module was introduced by J. H...
Poincare series for the algebras of joint invariants and covariants of n quadratic forms
We consider one of the fundamental objects of classical invariant theory, namely the Poincare series for an algebra of invariants of Lie group $SL_2$. The first two terms of the Laurent series expansion of Poincar\'e se...
Coupled fixed point theorems for weakly compatible mappings along with CLR property in Menger metric spaces
Coupled fixed point problems have attracted much attention in recent times. The aim of this paper is to extend the notions of E.A. property, CLR property and JCLR property for coupled mappings in Menger metric space and...
