Neutral set differential equations
The aim of this paper is to establish an existence and uniqueness result for a class of the set functional differential equations of neutral type where is a given function, is the family of all nonempty compact and convex subsets of a separable Banach space , denotes the space of all continuous set-valued functions from into , is the space of all integrally bounded set-valued functions , and is the Hukuhara derivative. The continuous dependence of solutions on initial data and...

Nonnegative solutions of a class of second order nonlinear differential equations
A differential equation of the form (q(t)k(u)u')' = λf(t)h(u)u' depending on the positive parameter λ is considered and nonnegative solutions u such that u(0) = 0, u(t) > 0 for t > 0 are studied. Some theorems about the existence, uniqueness and boundedness of solutions are given.

Nonuniqueness results for ordinary differential equations
In the present paper we give general nonuniqueness results which cover most of the known nonuniqueness criteria. In particular, we obtain a generalization of the nonuniqueness theorem of Chr. Nowak, of Samimi’s nonuniqueness theorem and of Stettner’s nonuniqueness criterion.
