Exact solutions of classical scalar field equations

We give a class of exact solutions of quartic scalar field theories. These solutions prove to be interesting as are characterized by the production of mass contributions arising from the nonlinear terms while maintaining a wavelike behavior. So, a quartic massless equation has a nonlinear wave solution with a dispersion relation of a massive wave and a quartic scalar theory gets its mass term r...

THE REGULARITY OF WEAK SOLUTIONS TO NONLINEAR SCALAR FIELD ELLIPTIC EQUATIONS CONTAINING p&q-LAPLACIANS

Abstract. In this paper, we consider the regularity of weak solutions u ∈ W (R ) ∩ W (R ) of the elliptic partial differential equation −∆pu−∆qu = f(x), x ∈ R , where 1 < q < p < N . We prove that these solutions are locally in C and decay exponentially at infinity. Furthermore, we prove the regularity for the solutions u ∈ W (R ) ∩W (R ) of the following equations −∆pu−∆qu = f(x, u), x ∈ R , w...

Scalar field–perfect fluid correspondence and nonlinear perturbation equations

The properties of dynamical Dark Energy (DE) and, in particular, the possibility that it can form or contribute to stable inhomogeneities, have been widely debated in recent literature, also in association to a possible coupling between DE and Dark Matter (DM). In order to clarify this issue, in this paper we present a general framework for the study of the nonlinear phases of structure formati...

Multiplicity of Positive Solutions for Nonlinear Field Equations in R

In this paper we study the multiplicity of positive solutions for nonlinear elliptic equations on R . The number of solutions is greater or equal than the number of disjoint intervals on which the nonlinear term is negative. Applications are given to multiplicity of standing waves for the nonlinear Schrödinger, Klein-Gordon and Klein-Gordon-Maxwell equations.

Exact Solutions for Nonlocal Nonlinear Field Equations in Cosmology

A method for the search of exact solutions for equation of a nonlocal scalar field in a non-flat metric is considered. In the Friedmann–Robertson–Walker metric the proposed method can be used in the case of an arbitrary potential, with the exception of linear and quadratic potentials, and allows to get in quadratures solutions, which depend on two arbitrary parameters. Exact solutions have been...
