A note on the controllability of higher-order linear systems
In this paper, a new condition for the controllability of higher order linear dynamical systems is obtained. The suggested test contains rank conditions of suitably defined matric...

Twin n-point boundary value problems
Abstract. We establish the existence of positive solutions to twin time-scale problems given by the dynamic equation -u (t) = a(t)f(u(t)), t (t1, tn) T with boundary conditions u...

Between quasi-convex and convex set-valued mappings
Abstract. The aim of this paper is to give sufficient conditions for a quasiconvex setvalued mapping to be convex. In particular, we recover several known characterizations of conv...

Well-posedness for a nonsmooth acoustic system
We consider an acoustic wave system with discontinuous coe cients and nonsmooth inputs. Existence, uniqueness and continuous dependence on input data of weak solutions are establi...
