Invariant Sets of Systems of Stochastic Differential Equations with JumpsNonlinear Oscillations - Tập 8 - Trang 233-239 - 2005
H. L. Kulinich, S. V. Kushnirenko
We introduce the notion of invariant surfaces for inhomogeneous stochastic differential equations with jumps. The results obtained enable one to determine invariant surfaces for stochastic differential equations of the type indicated.
On Goursat and Dirichlet problems for one equation of the third orderNonlinear Oscillations - Tập 11 - Trang 320-330 - 2009
T. D. Dzhuraev, O. S. Zikirov
We study the problem of the unique solvability of Goursat and Dirichlet problems for one partial differential equation of the third order. We construct a Riemann function for a linear third-order equation with a hyperbolic operator in the principal part, study some properties of the Riemann function, and then use them to prove theorems on the existence and uniqueness of a solution of the problems ...... hiện toàn bộ
Boundary-value problems for linear equations with a generalized invertible operator in a Banach space with basisNonlinear Oscillations - Tập 13 - Trang 558-568 - 2011
V. F. Zhuravlev
We consider linear boundary-value problems for operator equations with generalized invertible operators in Banach spaces that have bases. Using the technique of generalized inverse operators applied to generalized invertible operators in Banach spaces, we establish conditions for the solvability of linear boundary-value problems for these operator equations and obtain formulas for the representati...... hiện toàn bộ
