We use the same notations as in a previous paper [1]. Let / be a closed interval \j, δl={t\γύtύδ, ίeR}. Let C(/, C) denote the totality of complexvalued functions defined and of class C μ on / (μ=0, 1, •••, oo). Hereafter we fix some μ.For the sake of brevity, we denote O(/, C) by K(J), and K(J) n by M(J):Let X{t) be an nXh matrix whose components all belong to K(J):
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
