In this work, we study the existence of periodic solutions for a class of linear partial functional differential equations with infinite delay. Inspiring by an existing study, by applying the perturbation theory of semi-Fredholm operators, we introduce a

Quasi-Periodic Crystals—The Long Road from Discovery to Acceptance
[Extract] Three surprising discoveries on the nature of matter and its properties were published in the mid-1980s. All these discoveries led to Nobel prizes. The first discovery was in 1985, when fullerenes were discovered by Robert F.

PERIODIC ENVIRONMENTS AND PERIODIC HARVESTING
ABSTRACT. We consider autonomous population models under periodic harvesting and population models in periodic environments and seek conditions under which there is an asymptotically stable periodic solution.

Subcortical cytoskeleton periodicity throughout the nervous system
Superresolution fluorescence microscopy recently revealed a ~190 nm periodic cytoskeleton lattice consisting of actin, spectrin and other proteins underneath the membrane of cultured hippocampal neurons.

Periodicity and Quasi-Periodicity for Super-Integrable Hamiltonian Systems
Classical trajectories are calculated for two Hamiltonian systems with ring shaped potentials. Both systems are super-integrable, but not maximally super-integrable, having four globally defined single valued integrals of motion each.

Periodic Modules with Large Periods [PDF]
Let G be a nonabelian group of order p 3 {p^3} and exponent p, where p is an odd prime. Let K be a field of characteristic p. In this paper it is proved that there exist periodic KG-modules whose periods are 2p. Some examples of such modules are constructed.

Dynamical Analysis and Solutions of Nonlinear Difference Equations of Thirty Order
Discrete-time systems are sometimes used to explain natural phenomena that happen in nonlinear sciences. We study the periodicity, boundedness, oscillation, stability, and certain exact solutions of nonlinear difference equations in this paper. Using the
