Anti-periodic boundary value problems for Caputo-Fabrizio fractional impulsive differential equations [PDF]
In this paper, we shall discuss the existence and uniqueness of solutions for a nonlinear anti-periodic boundary value problem for fractional impulsive differential equations involving a Caputo-Fabrizio fractional derivative of order r ∈ (0, 1).

Self-gravitating scalar breathers with negative cosmological constant [PDF]
Breather-type (time-periodic and spatially localized) solutions with spherical symmetry are investigated in a massless scalar field theory coupled to Einstein's gravity with cosmological constant in $d$ spatial dimensions imposing anti de Sitter (AdS ...

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 orbits in Hamiltonian systems with involutory symmetries [PDF]
We study the existence of families of periodic solutions in a neighbourhood of a symmetric equilibrium point in two classes of Hamiltonian systems with involutory symmetries. In both classes, involutions reverse the sign of the Hamiltonian function.

Coupled-mode systems are used in physical literature to simplify the nonlinear Maxwell and Gross-Pitaevskii equations with a small periodic potential and to approximate localized solutions called gap solitons by analytical expressions involving ...

Anti-periodic solutions for semilinear evolution equations
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 ...
