Forced oscillation of impulsive fractional partial differential equations

Partial Differential Equations in Applied Mathematics, 2023
In this paper, we investigate the forced oscillation of impulsive fractional partial differential equations. Some sufficient conditions are established which guarantee that the oscillation of the solutions by applying the integral transformation ...

Modes of ocean variability in the tropical Pacific as derived from Geosat altimetry [PDF]

, 1994
Satellite-derived (Geosat altimetry) sea surface height anomalies for the period November 1986 to September 1989 were investigated in order to extract the dominant modes of climate variability in the tropical Pacific.

Interval Oscillation Criteria for Forced Second-Order Nonlinear Delay Dynamic Equations with Damping and Oscillatory Potential on Time Scales

International Journal of Differential Equations, 2016
We are concerned with the interval oscillation of general type of forced second-order nonlinear dynamic equation with oscillatory potential of the form rtg1xt,xΔtΔ+p(t)g2(x(t),xΔ(t))xΔ(t)+q(t)f(x(τ(t)))=e(t), on a time scale T.
