Translation of Time-Reversal Violation in the Neutral K-Meson System into a Table-Top Mechanical System

, 2012
Weak interactions break time-reversal (T) symmetry in the two-state system of neutral K mesons. We present and discuss a two-state mechanical system, a Foucault-type pendulum on a rotating table, for a full representation of K0 K0bar transitions by the ...

Oscillation of Half-Linear Differential Equations with Delay

Abstract and Applied Analysis, 2013
We study the half-linear delay differential equation , , We establish a new a priori bound for the nonoscillatory solution of this equation and utilize this bound to derive new oscillation criteria for this equation in terms of oscillation criteria for ...

Hopf bifurcation analysis of scalar implicit neutral delay differential equation

Electronic Journal of Qualitative Theory of Differential Equations, 2018
Hopf bifurcation analysis is conducted on a scalar implicit Neutral Delay Differential Equation (NDDE) by means of the extension of two analytical methods: 1) center manifold reduction combined with normal form theory; 2) method of multiple scales.

Differentiability of solutions of abstract neutral integro- differential equations

Journal of Integral Equations and Applications, 2013
This work is concerned with the regularity properties of solutions of abstract neutral integro-differential equations with infinite delay. The results are obtained by using a resolvent operator. Some different cases are discussed when the space is reflexive or has the Radon-Nikodym property.
