Logistic model for stock market bubbles and anti-bubbles [PDF]
Log-periodic power laws often occur as signatures of impending criticality of hierarchical systems in the physical sciences. It has been proposed that similar signatures may be apparent in the price evolution of financial markets as bubbles and the ...

Homogenized out-of-plane shear response three-scale fiber-reinforced composites [PDF]
In the present work we embrace a three scales asymptotic homogenization approach to investigate the effective behavior of hierarchical linear elastic composites reinforced by cylindrical, uniaxially aligned fibers and possessing a periodic structure at ...

Existence and uniqueness of anti-periodic solutions for a class of nonlinear n-th order functional differential equations [PDF]
In this paper, we use the method of coincide degree theory to establish new results on the existence and uniqueness of anti-periodic solutions for a class of nonlinear \(n\)-th order functional differential equations of the form \[x^{(n)}(t)=F(t, x_t, x^{

Exact solution and interfacial tension of the six-vertex model with anti-periodic boundary conditions [PDF]
We consider the six-vertex model with anti-periodic boundary conditions across a finite strip. The row-to-row transfer matrix is diagonalised by the `commuting transfer matrices' method.

Anti-periodic solutions for nonlinear evolution inclusions
The authors consider the nonlinear anti-periodic evolution inclusion \[ \begin{aligned} & -u'(t)\in A(t,u(t))+F(t,u(t))\text{ a.e. on }I=[0,T],\\ & u(0)=-u(T),\end{aligned}\eqno{(1)} \] where \(\left( X,H,X^{\ast }\right) \) is an evolution triple, \(A:I\times X\rightarrow 2^{X^{\ast }}\) and \(F:I\times X\rightarrow 2^{H}\). \ It is not assumed that \(

A class of Clifford-valued high-order Hopfield neural networks (HHNNs) with state-dependent and leakage delays is considered. First, by using a continuation theorem of coincidence degree theory and the Wirtinger inequality, we obtain the existence of ...

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.

Delay-induced Synchronization Phenomena in an Array of Globally Coupled Logistic Maps [PDF]
We study the synchronization of a linear array of globally coupled identical logistic maps. We consider a time-delayed coupling that takes into account the finite velocity of propagation of the interactions.
