WebbSlowly Varying Envelopes We'll assume that the wave won't be dramatically affected by the induced polarization, so the wave won’t change too much. Assume Specifically, the envelopes, E 0 and P 0, are assumed to vary slowly, and the fast variations will all be in the complex exponentials, Ext E x j kx t Pxt P x j kx t(,) ()exp (,) ()exp Webb29 mars 2006 · On slowly-varying Stokes waves - Volume 41 Issue 4.

WebbSlowly varying system ẋ = A (t)x. Abstract: A limiting case of great importance in engineering is that of slowly varying parameters. For systems described by \dot {x} = A (t)x , one would intuitively expect that if, for each t , the frozen system is stable, then the time-varying system should also be stable. Provided A (t) is small enough ...

Definition (Jakimczuk): Suppose that f ( x) > 0, lim x → ∞ f ( x) = ∞, and there exists a continuous derivative f ′ ( x) > 0. The function f ( x) is of slow increase if (2) lim x → ∞ f ′ ( x) f ( x) / x = 0. peanuts lighted christmas tree
