The Method of Multiple Time Scales and Finite Differences Method for the van der Pol Oscillator with Small Fractional Damping
Journal Title: Asian Research Journal of Mathematics - Year 2017, Vol 2, Issue 2
Abstract
In this paper, we consider the van der Pol oscillator with small fractional damping. To construct the approximate and numerical solutions of the equation, the method of multiple time scales and finite differences method are used, respectively. It is shown that the approximate solution is in good agreement with the numerical solution for weakly nonlinear case and the fractional derivative order has meaningful effects on natural frequencies of the oscillator.

The 19 Densities of the Hierarchical Bayes Model with Two Conditional Levels
There are 19 densities involved in the hierarchical Bayes model with two conditional levels, in which the 3 densities, that is, the likelihood function, the first level prior density, and the secondlevel prior density, a...
Decay for Solutions to Semilinear Regularity-Loss Type Equations with Memory
In this paper we consider the initial value problem of an inertial model for a generalized semilinear plate equation with memory in Rn (n ≥ 1). We study the decay and the regularity-loss property for this type of equatio...
Unconditional Integrability with Application to Ergodic Theorem
We present a straightforward introduction to the unconditional integrability in the extended sense. We state and proof useful necessary and sufficient conditions for unconditional integrability of complex or real valued...
