Representation of the Solution of Goursat Problem for Second Order Linear Stochastic Hyperbolic Differential Equations

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2021
The article considers second-order system of linear stochastic partial differential equations of hyperbolic type with Goursat boundary conditions. Earlier, in a number of papers, representations of the solution Goursat problem for linear stochastic ...

On one solution of a periodic boundary value problem for a hyperbolic equations [PDF]

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2023
In a rectangular domain, we consider a boundary value problem periodic in one variable for a system of partial differential equations of hyperbolic type. Introducing a new unknown function, this problem is reduced to an equivalent boundary value

A Reduced-Order Extrapolation Spectral-Finite Difference Scheme Based on the POD Method for 2D Second-Order Hyperbolic Equations

open access: yesMathematical Modelling and Analysis, 2017
In this study, a reduced-order extrapolation spectral-finite difference (ROESFD) scheme based on the proper orthogonal decomposition (POD) method is set up for the two-dimensional (2D) second-order hyperbolic equations.

Scalar differential invariants of symplectic Monge–Ampère equations [PDF]

open access: yes, 2011
All second order scalar differential invariants of symplectic hyperbolic and elliptic Monge-Ampère PDEs with respect to symplectomorphisms are explicitly computed. In particular, it is shown that the number of independent second order invariants is equal
