This note shows that fur a BVP of Poisson's equation with Qm(u,v) as its source function, a direct evaluation of some integrals yields the same exact result
The minimization of nonconvex, nondifferentiable functions that are compositions of max-type functions formed by nondifferentiable convex functions is discussed
In this paper, weconsider the evolution of a soliton when dissipative lose exists. By means of non-perturbed method, an exact envelope wave solution of nonlimea
