Anti-periodic solutions for second order differential equations
The authors consider the existence of anti-periodic solutions for the following second order differential equation \[ (p(t)x')'+f(t,x)=0,\tag{1} \] where \(p\in C^1(\mathbb R)\) is a given \(T\)-periodic function, and \(p(t)>0\); \(f\in C^1(\mathbb R\times\mathbb R)\) is a \(T\)-anti-periodic function.

From Instantons to Sphalerons: Time-Dependent Periodic Solutions of SU(2)-Higgs Theory [PDF]
We solve numerically for periodic, spherically symmetric, classical solutions of SU(2)-Higgs theory in four-dimensional Euclidean space. In the limit of short periods the solutions approach tiny instanton-anti-instanton superpositions while, for longer ...

On Antiperiodic Boundary Value Problems for Higher-Order Fractional Differential Equations
We study an antiperiodic boundary value problem of nonlinear fractional differential equations of order q∈(4,5]. Some existence results are obtained by applying some standard tools of fixed-point theory.

Magnetic Monopoles in String Theory [PDF]
Magnetic monopole solutions to heterotic string theory are discussed in toroidal compactifications to four spacetime dimensions. Particular emphasis is placed on the relation to previously studied fivebrane solutions in ten dimensions and on the ...

Synchronous motion of two vertically excited planar elastic pendula [PDF]
The dynamics of two planar elastic pendula mounted on the horizontally excited platform have been studied. We give evidence that the pendula can exhibit synchronous oscillatory and rotation motion and show that stable in-phase and anti-phase synchronous ...

Breathers in the weakly coupled topological discrete sine-Gordon system [PDF]
Existence of breather (spatially localized, time periodic, oscillatory) solutions of the topological discrete sine-Gordon (TDSG) system, in the regime of weak coupling, is proved.

Isolating Segments and Anti-Periodic Solutions
Using the technique based on the notion of periodic isolating segments, the author establishes a sufficient condition for the existence of \(2^n\) geometrically distinct solutions of the two-point boundary value problem \[ \dot{x}=f(t,x), \qquad x(0)=g(x(nT)), \] where \(f\) is a smooth vector field on the manifold \(M\) and \(n\) is a positive integer.

Anti-Periodic Solutions for Neural Networks with Delays and Impulses [PDF]
In this paper we investigate a class of artificial neural networks with delays subject to periodic impulses. By exploiting Lyapunov functions, we analyze the global exponential stability of an arbitrary solution with initial value being bounded by Υ .

Periodic Travelling Waves in Dimer Granular Chains
We study bifurcations of periodic travelling waves in granular dimer chains from the anti-continuum limit, when the mass ratio between the light and heavy beads is zero.
