We prove that for each Polish space X , the space C(X) of continuous real-valued functions on X satisfies (a strong version of) the Pytkeev property, if endowed with the compactopen topology. We also consider the Pytkeev property in the case where C(X) is endowed with the topology of pointwise convergence.

Abstract Given a ring endowed with order, we provide sufficient conditions for the order topology induced by to become (analogous results module orders are consequently derived). Finally, notions of Radon and regular measures transported scope module-valued through orders. Classical characterizations these obtained as well hereditariness regularity conditional ring-valued measures.

In this paper, we introduce the new definition of rough membership function using continues and discuss several concepts properties continuous set value functions as results on . Moreover, extend to topology spaces by substituted an equivalence class prove some theorems certain types more general fundamental generalized sets. Our result concept valued theory.

Let X,Y be locally convex spaces and L(X,Y ) the space of continuous linear operators from X into Y . We consider 2 types of multiplier convergent theorems for a series P Tk in L(X,Y ). First, if λ is a scalar sequence space, we say that the series P Tk is λ multiplier convergent for a locally convex topology τ on L(X,Y ) if the series P tkTk is τ convergent for every t = {tk} ∈ λ. We establish...

The original definition of a topological space given by Hausdorff used neighborhood systems. Lattice-valued maps appear in this context when you identify a topology with a monoid in the Kleisli category of the filter monad on SET. H?hle’s notion of a lattice-valued topology [2] uses the same idea and it’s inspired in the classical lattice-valued topologies. Ltopological spaces are motivated by ...

We derive new representations for the generalised Jacobian of a locally Lipschitz map between finite dimensional real Euclidean spaces as lower limit (i.e., inferior) classical derivative where it exists. The lead to significantly shorter proofs basic properties subgradient and including chain rule. establish that sequence maps converges given in L-topology—that is, weakest refinement sup norm ...

The notion of sobriety is extended to the realm topological spaces valued in a commutative and unital quantale, via an adjunction between category quantale modules quantale-valued spaces. Relations such sober domains based on flat ideals are investigated. In particular, it shown that if unit element coincides with its top element, then every domain (relative ideals) Scott topology space.

In this article, we study the coding problem for real-valued Lévy processes X (original) under Lp[0, 1]-norm distortion for some fixed p ∈ [1,∞). Here we think of X being a D[0,∞)-valued process, where D[0,∞) denotes the space of càdlàg functions endowed with the Skorohod topology. We shall denote by ‖ · ‖ the standard Lp[0, 1]-norm. Let 0 < s ≤ ∞. The objective is now to find a càdlàg real-val...

In this paper, we shall describe about a fuzzy estimation theory based on the concept of set-valued operators, suitable for available operation of extremely complicated large-scale network systems. Fundamental conditions for availability of system behaviors of such network systems are clarified in a form of β-level fixed point theorem for system of fuzzy-set-valued operators. Here, the proof of...
