Periodic Boundary Value Problems for Second-Order Functional Differential Equations
Upper and lower solution method plays an important role in studying boundary value problems for nonlinear differential equations; see 1 and the references therein. Recently, many authors are devoted to extend its applications to boundary value problems of functional differential equations 2–5 . Suppose α is one upper solution or lower solution of periodic boundary value problems for second-orde...

Usage of fuzzy differential equations (FDEs) is a natural way to model dynamical systems under possibilistic uncertainty. We consider second order hybrid fuzzy differentia

در این رساله به بررسی رفتار جواب های رده ای از معادلات دیفرانسیل با مشتقات جزیی در دامنه های کراندار می پردازیم . این معادلات به فرم نیم-خطی و غیر خطی برای مسایل مستقیم و معکوس مورد مطالعه قرار می گیرند . به ویژه، تاثیر شرایط مختلف فیزیکی را در مساله، نظیر وجود موانع و منابع، پراکندگی و چسبندگی در معادلات موج و گرما بررسی می کنیم و به دنبال شرایطی می گردیم که متضمن وجود سراسری یا عدم وجود سراسر...
On Boundary Value Problems for Systems of Ordinary, Nonlinear, Second Order Differential Equations^)
where x and z are vectors (not necessarily of the same dimension). 1. Below, if x, f are vectors, \x\ denotes the Euclidean length of x and x-f the scalar product of x and/. In §§1—5, there will be obtained a priori bounds for the first derivatives of w-vector functions x(t) subject to second order differential inequalities. In this direction, our results are new only for n> 1. For reference an...
