For the problem considered here we obtain estimates of solutions of neutral type functional-differential inclusions analogous to the Filippov’s estimates (see [6, 7, 8, 9, 10]), and

The focus of our present work is to establish the existence of almost periodic solutions of neutral functional differential equations by using the Razumikhin-type argument.. The
they applied the criteria to show the existence of periodic and almost periodic solutions for some partial functional differential equations with infinite delay and some
EJQTDE, 2004 No.. We will deal with a first order func- tional boundary value problem on an infinite interval, seeking positive non-zero solutions. In Section 1 we state the
In the present study, using the characterizations of measures of noncompactness we prove a theorem on the existence and local asymptotic stability of solutions for a
the Korteweg-de Vries Burgers (KdVB) equations with initial conditions by a homotopy approach.. Numerical solutions obtained by homotopy analysis method are compared with
Previous extensions to the SPP include, in separate models, the simultaneous determination of the optimal price and quantity when demand is price-dependent, and the determination of
