Quasilinear hyperbolic equations with hysteresis
Plasticity, ferromagnetism, ferroelectricity and other phenomena lead to quasi-linear hyperbolic equations of the form \frac{\partial ^{2}}{\partial t^{2}}\left[u + F\left(u\right)\right] + Au = f, where is a (possibly discontinuous) hysteresis operator, and

A new method of imposing boundary conditions for hyperbolic equations [PDF]
A new method to impose boundary conditions for pseudospectral approximations to hyperbolic equations is suggested. This method involves the collocation of the equation at the boundary nodes as well as satisfying boundary conditions.

Mixed problem for a third order parabolic-hyperbolic model equation
In 1978, the journal Differential Equations published an article by A.M. Nakhushev, that presented a method for correctly formulating a boundary value problem for a class of second-order parabolic-hyperbolic equations in an arbitrarily bounded domain ...

Some theoretical results for a class of neural mass equations
We study the neural field equations introduced by Chossat and Faugeras in their article to model the representation and the processing of image edges and textures in the hypercolumns of the cortical area V1.

Transcendental Equations for Nonlinear Optimization in Hyperbolic Space
We present a novel application of transcendental equations for nonlinear distance optimization in hyperbolic space. Through asymptotic approximations using Fourier and Taylor series expansions, we obtain approximations for the transcendental equations ...

A parabolic-hyperbolic free boundary problem modeling tumor growth with drug application
In this article, we study a free boundary problem modeling the growth of tumors with drug application. The model consists of two nonlinear second-order parabolic equations describing the diffusion of nutrient and drug concentration, and three ...

Manifold spines and hyperbolicity equations
The authors present a combinatorial representaion of gluing 3-manifolds and their special spines. This is done using graphs encoded by \(\gamma\)-tuples of non-negative integers. More precisely, they use the result of Casler which states that two 3-manifolds with homeomorphic special spines are homeomorphic.

Nonlinear multidimensional parabolic-hyperbolic equations
This paper deals with the coupling of a quasilinear parabolic problem with a first order hyperbolic one in a multidimensional bounded domain $Omega$. In a region $Omega_{p}$ a diffusion-advection-reaction type equation is set while in the complementary ...
