On the Controllability for Second Order Hyperbolic Equations in Curved Polygons

open access: greenTrends in Computational and Applied Mathematics, 2007
In this work we study exact boundary controllability for a class of hyperbolic linear partial differential equation with constant coefficient which includes the linear Klein-Gordon equation.

Contact Geometry of Hyperbolic Equations of Generic Type [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2008
We study the contact geometry of scalar second order hyperbolic equations in the plane of generic type. Following a derivation of parametrized contact-invariants to distinguish Monge-Ampère (class 6-6), Goursat (class 6-7) and generic (class 7-7 ...

Cosine Methods for Nonlinear Second-Order Hyperbolic Equations [PDF]

open access: bronzeMathematics of Computation, 1989
We construct and analyze efficient, high-order accurate methods for approximating the smooth solutions of a class of nonlinear, second-order hyperbolic equations. The methods are based on Galerkin type discretizations in space and on a class of fourth-order accurate two-step schemes in time generated by rational approximations to the cosine ...

Simultaneous exact controllability for Maxwell equations and for a second-order hyperbolic system

open access: greenElectronic Journal of Differential Equations, 2010
We present a result on "simultaneous" exact controllability for two models that describe two hyperbolic dynamics. One is the system of Maxwell equations and the other a vector-wave equation with a pressure term.

A numerical Haar wavelet-finite difference hybrid method and its convergence for nonlinear hyperbolic partial differential equation

open access: yesDemonstratio Mathematica, 2023
In this research work, we proposed a Haar wavelet collocation method (HWCM) for the numerical solution of first- and second-order nonlinear hyperbolic equations. The time derivative in the governing equations is approximated by a finite difference.
