Oscillation Criteria of Singular Initial-Value Problem for Second Order Nonlinear Dynamic Equation on Time Scales

open access: yesNonautonomous Dynamical Systems, 2018
By using of generalized Opial’s type inequality on time scales, a new oscillation criterion is given for a singular initial-value problem of second-order dynamic equation on time scales. Some oscillatory results of its generalizations are also presented.

Dynamics near QCD critical point by dynamic renormalization group [PDF]

open access: yes, 2011
We work out the basic analysis of dynamics near QCD critical point (CP) by dynamic renormalization group (RG). In addition to the RG analysis by coarse graining, we construct the nonlinear Langevin equation as a basic equation for the critical dynamics ...

Dynamic Transitions for Quasilinear Systems and Cahn-Hilliard equation with Onsager mobility [PDF]

open access: yes, 2011
The main objectives of this article are two-fold. First, we study the effect of the nonlinear Onsager mobility on the phase transition and on the well-posedness of the Cahn-Hilliard equation modeling a binary system.

Conditional oscillation of half-linear Euler-type dynamic equations on time scales

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2015
We investigate second-order half-linear Euler-type dynamic equations on time scales with positive periodic coefficients. We show that these equations are conditionally oscillatory, i.e., there exists a sharp borderline (a constant given by the ...

The asymptotic properties of the dynamic equation with a delayed argument [PDF]

open access: yesOpuscula Mathematica, 2006
In this paper, we present some asymptotic results related to the scalar dynamic equation with a delayed argument. Using the time scale calculus we generalize some results known in the differential and difference case to the more general dynamic case.
