Determining the waveguide conductivity in a hyperbolic equation from a single measurement on the lateral boundary [PDF]
, 2015 We consider the multidimensional inverse problem of determining the conductivity coefficient of a hyperbolic equation in an infinite cylindrical domain, from a single boundary observation of the solution.

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2014 We consider the Cauchy problem for the hyperbolic differential equation of the forth order with nonmultiple characteristics. We generalize this problem from the similar Cauchy problem for the hyperbolic differential equation of the third order with ...

Uniform stabilization of a coupled structural acoustic system by boundary dissipation
Abstract and Applied Analysis, 1998 We consider a coupled PDE system arising in noise reduction problems. In a two dimensional chamber, the acoustic pressure (unwanted noise) is represented by a hyperbolic wave equation.

Spectral problem for the sixth order nonclassical differential equations
Қарағанды университетінің хабаршысы. Математика сериясы, 2020 In this article we investigate the correctness of boundary value problems for a sixth order quasi-hyperbolic equation in the Sobolev space Lu = −D6t u + ∆u − λu (Dt =∂/∂t , ∆ = Σni=1∂2/∂x2i – Laplace operator, λ – real parameter). For the given operator

The Existence of a Unique Solution of the Hyperbolic Functional Differential Equation
Demonstratio Mathematica, 2014 We consider the Z. Szmydt problem for the hyperbolic functional differential equation. We prove a theorem on existence of a unique classical solution and the Carathéodory solution of the hyperbolic equation.

Continuous dependence estimate for a degenerate parabolic–hyperbolic equation with Lévy noise [PDF]
, 2016 In this article, we are concerned with a multidimensional degenerate parabolic–hyperbolic equation driven by Lévy processes. Using bounded variation (BV) estimates for vanishing viscosity approximations, we derive an explicit continuous dependence ...

On Solving Hyperbolic Trajectory Using New Predictor-Corrector Quadrature Algorithms
مجلة بغداد للعلوم, 2014 In this Paper, we proposed two new predictor corrector methods for solving Kepler's equation in hyperbolic case using quadrature formula which plays an important and significant rule in the evaluation of the integrals.
