In this paper, necessary and sufficient conditions for the existence of nonoscillatory solutions of the forced nonlinear difference equation âˆ†(xn âˆ’ pnxÏ„(n)) + f(n, xÏƒ(n)) = qn are obtained. Examplesâ€¦ (More)

Dual-signal-wave optical parametric oscillators (DSW OPOs) around 1.5 mum by using two periodically poled crystals was demonstrated experimentally. The widely tunable wavelength interval from 2.5 nmâ€¦ (More)

In this paper, we study the existence of oscillatory and nonoscillatory solutions of neutral differential equations of the form ( x(t)âˆ’ cx(tâˆ’ r))â€² Â± (P (t)x(tâˆ’ Î¸)âˆ’Q(t)x(tâˆ’ Î´)) = 0 where c > 0, r > 0,â€¦ (More)
