Winding number and non-BPS bound states of walls in nonlinear sigma models [PDF]
, 2002 Non-supersymmetric multi-wall configurations are generically unstable. It is proposed that the stabilization in compact space can be achieved by introducing a winding number into the model. A BPS-like bound is studied for the energy of configuration with

Anti-periodic solutions for semilinear evolution equations
Journal of Mathematical Analysis and Applications, 2006 The author considers the following semilinear evolution equation \[ \begin{cases} u'(t)+Au(t)+\partial Gu(t)+F(t,u(t))=0 &\text{a.e. }t\in \mathbb{R},\\ u(t+T)=-u(t), &t\in \mathbb{R},\end{cases} \tag{1} \] in a separable Hilbert space \(H\). He proves that if \(A:D(A) \subset H\to H\) is a linear densely defined closed selfadjoint operator such that ...

Next nearest neighbour Ising models on random graphs
, 2012 This paper develops results for the next nearest neighbour Ising model on random graphs. Besides being an essential ingredient in classic models for frustrated systems, second neighbour interactions interactions arise naturally in several applications ...

The Center symmetry and its spontaneous breakdown at high temperatures [PDF]
, 2000 We examine the role of the center Z(N) of the gauge group SU(N) in gauge theories. In this pedagogical article, we discuss, among other topics, the center symmetry and confinement and deconfinement in gauge theories and associated finite-temperature ...

EXISTENCE RESULTS OF SOLUTIONS FOR ANTI-PERIODIC FRACTIONAL LANGEVIN EQUATION
Journal of Applied Analysis & Computation, 2020 In this paper, the author studies the existence and uniqueness results of a fractional Langevin equation with anti-periodic and nonlocal integral boundary conditions. By means of the technique of the Green's function, the existence and uniqueness of solution is proved by the Banach fixed point theorem, and the existence of at least one positive ...

Parametrically forced sine-Gordon equation and domain walls dynamics in ferromagnets
, 1998 A parametrically forced sine-Gordon equation with a fast periodic {\em mean-zero} forcing is considered. It is shown that $\pi$-kinks represent a class of solitary-wave solutions of the equation.

Boundary Conditions in Stepwise Sine-Gordon Equation and Multi-Soliton Solutions [PDF]
, 2007 We study the stepwise sine-Gordon equation, in which the system parameter is different for positive and negative values of the scalar field. By applying appropriate boundary conditions, we derive relations between the soliton velocities before and after ...

The new optical behaviour of the LPD model with Kerr law and parabolic law of nonlinearity
Partial Differential Equations in Applied Mathematics, 2022 In this paper, the newly obtained optical analytical solutions of the Lakshmanan–Porsezian–Daniel model with two forms of nonlinearity is investigated. These are Kerr law and parabolic law of nonlinearity. The novel analytical method namely, the modified
