A function continuous on a closed interval is bounded on that interval and attains its greatest and least value. Moreover, on this interval it takes on all values between its least and greatest values. Functions continuous on a closed interval are uniformly continuous (on that interval). Every...
摘要: We present an iterative method for constructing additive envelopes of continuous functions on a compact set, with contact at a specified point. For elements of a class of submodular functions we provide closed-form expressions for such additive envelopes....
On Approximate Recovery of Functions with Bounded Mixed Derivative Let F denote a class of continuous functions on Π d =[0,2π] d . For 1≤p≤∞, ξ=(ξ 1 ,,ξ m ) with ξ j ∈Π d and ψ=(ψ 1 ,,ψ m ) with ψ j ∈L p (... VN Temlyakov - 《Journal of Complexit...
In the case when E is compact, we refer to elements of C(E,E′) as continuous functions since, by Corollary 5.26, every continuous function from a compact metric space to a metric space is bounded. It is useful to consider the collection B(E,E′) of all bounded functions from E to...
on x(t) denotes the posibility of having recurrent connections. The full proof of theorem 1 is given in Methods. The theorem formally demonstrates that the approximated closed-form solution for the given LTC system is given by equation (2) and that this approximation is tightly bounded with ...
Let X be completely regular Hausdorff space, E a Hausdorff locally convex space, C(X, E) (Cb(X, E)) the space of all E-valued (all E-valued bounded) continuous functions on X, and βz a strict topology on Cb(X, E). It is proved that a sequence {n} in (Cb(X, E), βz...
To give an example, if f:\mathbb{R} \rightarrow \mathbb{R} is the function defined by setting f(x)=1 when x= 0 and f(x)=0 when x\ne 0, then one has \underset{x\rightarrow 0 ; x\in \mathbb{R} /\{0\}}{lim} f(x)=0, but \underset{x\rightarrow 0}{lim} f(x) ...
