Piecewise Euclidean Structures and Eberlein's Rigidity Theorem in the Singular Case [PDF]
, 1999 In this article, we generalize Eberlein’s Rigidity Theorem to the singular case, namely, one of the spaces is only assumed to be a CAT(0) topological manifold.

A FUNCTIONAL DIFFERENTIAL EQUATION IN BANACH SPACES
, 1982 The study of the Cauchy problem for differential and functional differential equations in a Banach space relat ive to the strong topology has attracted much attention in recent years [10] , [11] . However a similar study of the Cauohy problem in a Banaoh

On the properties of the solution set map to Volterra integral inclusion
, 2017 For the multivalued Volterra integral equation defined in a Banach space, the set of solutions is proved to be $R_\delta$, without auxiliary conditions imposed in Theorem 6 [J. Math. Anal. Appl. 403 (2013), 643-666]. It is shown that the solution set map,

Different Types of Weighted Composition Operators on Banach Spaces of Analytic Functions [PDF]
, 2023 Many problems in real life are, at least approximatively, of linear nature and can be mathematically examined with the aid of linear spaces. It is natural to measure the size of objects occurring in the problems and such an operation is called a norm. If

Convergence of an implicit–explicit midpoint scheme for computational micromagnetics [PDF]
, 2017 Based on lowest-order finite elements in space, we consider the numerical integration of the Landau–Lifschitz–Gilbert equation (LLG). The dynamics of LLG is driven by the so-called effective field which usually consists of the exchange field, the ...

An extension of the Krein-Smulian theorem.
, 2006 Let X be a Banach space, u ∈ X ∗∗ and K,Z two subsets of X ∗∗ .Denote by d ( u,Z )and d ( K,Z ) the distances to Z from the point u and from the subset K respectively.

On the Krein-Šmulian theorem for weaker topologies
, 2003 We investigate possible extensions of the classical KreinSmulian theorem to various weak topologies. In particular, if X is a WCG Banach space and τ is any locally convex topology weaker than the norm-topology, then for every τ -compact norm-bounded set ...

Representing groups against all odds [PDF]
, 2017 We investigate how probability tools can be useful to study representations of non-amenable groups. A suitable notion of "probabilistic subgroup" is proposed for locally compact groups, and is valuable to induction of representations.

, 1986 PROOF. Let {xi} be a dense subset of X. Suppose that d(x**, JX) = d > 0. By the Hahn-Banach theorem there is a norm one functional x*** satisfying x***(JX) =0 and x***(x**)= d. Let Wn = {z*: Iz*(xi)l d/2} n W,.
