Difference methods for nonlinear first-order hyperbolic systems of equations [PDF]
Mathematics of Computation, 1970 Two difference methods for approximating some first-order nonlinear hyperbolic differential equations are considered. The methods apply to problems arising in a number of physical applications. Each of the methods is explicit and can be implemented on a computer easily. It is proved that the methods are first-order convergent in the maximum norm.

Estimation of Cauchy data for a first-order nonlinear hyperbolic equation
Journal of Mathematical Analysis and Applications, 1988 The authors study the Cauchy problem: \[ u_ t+uu_ x+au=\phi(x,t)\text{ in } \Omega \times (0,t),\;u(x,0)=u_ 0(x), \] where \(\Omega\) is an open interval in \({\mathbb{R}}\). This system is associated with an initial value problem for the system: \[ dx/dt=z,\quad dz/dt=-az+\phi (x,t). \] Suppose that M observations \(\{z_ k\}^ M_{k=1}\) at positions \(\

Demonstratio 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.

Mathematical Biosciences and Engineering, 2021 We investigate the propagation of uncertainties in the Aw-Rascle-Zhang model, which belongs to a class of second order traffic flow models described by a system of nonlinear hyperbolic equations. The stochastic quantities are expanded in terms of wavelet-

Networks and Heterogeneous Media, 2021 In the first part of this series, an augmented PDE system was introduced in order to couple two nonlinear hyperbolic equations together. This formulation allowed the authors, based on Dafermos's self-similar viscosity method, to establish the existence ...
