Non-polynomial Fourth Order Equations which Pass the Painlev´e Test Fahd Jrad

Recently, systems of linear differential equations were solved using variational iteration method [1], differ- ential transformation method [2], Adomian decompo- sition method

In recent years, various powerful methods have been developed to construct exact solitary wave solutions and periodic wave so- lutions of the nonlinear evolution equations (NLEEs),

64a, 420 – 430 (2009); received September 4, 2008 / revised October 14, 2008 In this work, the homotopy perturbation method proposed by Ji-Huan He [1] is applied to solve both

and parabolic partial differential equations subject to temperature overspecification [26], the second kind of nonlinear integral equations [27], nonlinear equations arising in

We present a necessary and sufficient criterion for the flow of an analytic ordinary differential equation to be strongly monotone; equivalently, strongly order-preserving1.

Or we may wish to prescribe the excentricity e~ of the surfaces of constant density at the center of the ellipsoids (considered known !rom hydrostatic theory, see below).

The construction with lifting of the direction field gives a possibility to reduce the classification of characteristic net singularities of generic linear second order mixed type

In other words, we combine the two approaches by changing the sought object (an input instead of a state) in an observation problem, or, symmetrically, the desired
