Nonexistence of global solutions to system of semi-linear fractional evolution equations

Universal Journal of Mathematics and Applications, 2018
In this research we are interested to Cauchy problem for system of semi-linear fractional evolution equations. Some authors were concerned with studying of global existence of solutions for the hyperbolic nonlinear equations with a damping term. Our goal

Well-posedness of the Dirichlet and Poincaré problems for one class of hyperbolic equations in a multidimensional domain

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2017
In early works the author studied the Dirichlet and Poincaré problems for multidimensional hyperbolic equations, which shows the well-posedness of these problems in cylindrical domains, significantly dependent on the height of the considered cylindrical ...

Local well-posedness for membranes in the light cone gauge

, 2009
In this paper we consider the classical initial value problem for the bosonic membrane in light cone gauge. A Hamiltonian reduction gives a system with one constraint, the area preserving constraint.

Generalized Hyperbolic Function Solution to a Class of Nonlinear Schrödinger-Type Equations

Journal of Applied Mathematics, 2012
With the help of the generalized hyperbolic function, the subsidiary ordinary differential equation method is improved and proposed to construct exact traveling wave solutions of the nonlinear partial differential equations in a unified way.

Relativistic MHD and black hole excision: Formulation and initial tests

, 2005
A new algorithm for solving the general relativistic MHD equations is described in this paper. We design our scheme to incorporate black hole excision with smooth boundaries, and to simplify solving the combined Einstein and MHD equations with AMR.

Harmonic fields on the extended projective disc and a problem in optics

, 2007
The Hodge equations for 1-forms are studied on Beltrami's projective disc model for hyperbolic space. Ideal points lying beyond projective infinity arise naturally in both the geometric and analytic arguments.

Time discretization of an abstract problem from linearized equations of a coupled sound and heat flow

Electronic Journal of Differential Equations, 2020
Recently, a time discretization of simultaneous abstract evolution equations applied to parabolic-hyperbolic phase-field systems has been studied. This article focuses on a time discretization of an abstract problem that has application to linearized
