First-order optical systems with real eigenvalues
, 2007 It is shown that a lossless first-order optical system whose real symplectic ray transformation matrix can be diagonalized and has only real eigenvalues, is similar to a separable hyperbolic expander in the sense that the respective ray transformation ...

Известия Иркутского государственного университета: Серия "Математика", 2014 In this paper an optimal control problem is considered, where the controlled process is described by a non-linear wave equation. The state vector consists of the solution for the non-linear wave equation and its first-order partial derivatives with ...

Solutions to a first order hyperbolic system
Surveys in Mathematics and its Applications, 2018 Summary: The study of small perturbations in the shock initiation of an inviscid compressible fluid with chemical reaction leads to a first order hyperbolic system of two equations. The order zero approximation of the system involves only constant coefficients.

Multidimensional first and second order symmetric strang splitting for hyperbolic systems [PDF]
, 2008 We propose an algebraic basis for symmetric Strang splitting for first and second order accurate schemes for hyperbolic systems in N dimensions. Examples are given for two and three dimensions. Optimal stability is shown for symmetric systems.

First-order symmetrizable hyperbolic formulations of Einstein's equations including lapse and shift as dynamical fields [PDF]
, 2002 First-order hyperbolic systems are promising as a basis for numerical integration of Einstein's equations. In previous work, the lapse and shift have typically not been considered part of the hyperbolic system and have been prescribed independently. This

Modern Control Methods for First Order Hyperbolic Partial Differential Equations
, 2016 This work is focused on two control methods for first order hyperbolic partial differential equations (PDE). The first method investigated is output regulation by employing the internal model control (IMC) principle where the controller generates the ...
