An Elementary Example of a Banach Space Not Isomorphic to Its Complex Conjugate
We give a simple and explicit example of a complex Banach space which is not isomorphic to its complex conjugate, and hence of two real-isomorphic spaces which are not complex-isomorphic. If X is a complex Banach space, its complex conjugate X̄ is defined to be the space X equipped with the alternative scalar multiplication α ⊗ x = ᾱx. In [1] Bourgain gave the first example of a complex Banach s...
متن کاملan investigation of the impact of self monitoring on langauge teachers motivational practice and its effect on learners motivation
the central purpose of this study was to conduct a case study about the role of self monitoring in teacher’s use of motivational strategies. furthermore it focused on how these strategies affected students’ motivational behavior. although many studies have been done to investigate teachers’ motivational strategies use (cheng & d?rnyei, 2007; d?rnyei & csizer, 1998; green, 2001, guilloteaux & d?...
An example of a C 1 , 1 function , which is not a d . c . function
Let X = lp, p ∈ (2,+∞). We construct a function f : X → R which has Lipschitz Fréchet derivative on X but is not a d.c. function.
متن کاملAn Example of a C-minimal Group Which Is Not Abelian-by-finite
In 1996 D. Macpherson and C. Steinhorn introduced C-minimality as an analogue, for valued fields and some groups with a definable chain of normal subgroups with trivial intersection, of the notion of o-minimality. One of the open questions of that paper was the existence of a non abelian-by-finite C-minimal group. We give here the first example of such a group.
متن کاملAn Example of a Differentiability Space Which Is Pi-unrectifiable
We construct a (Lipschitz) differentiability space which has at generic points a disconnected tangent and thus does not contain positive measure subsets isometric to positive measure subsets of spaces admitting a Poincaré inequality. We also prove that l-valued Lipschitz maps are differentiable a.e., but there are also Lipschitz maps taking values in some other Banach spaces having the Radon-Ni...
