WebAbstract. In this note we study the problem how the complexification of a real Banach space can be normed in such a way that it becomes a complex Banach space from the point of view of the theory of cross-norms on tensor products of Banach spaces. In particular we show that the norm of a complex Banach lattice can be interpretated in terms of ... WebBanach space definition, a vector space on which a norm is defined that is complete. See more.
Web3. Fractal Interpolation in Banach Spaces and Algebras. In this section, we give very general conditions for the existence of a fractal curve with values on a Banach space. We use the term “curve” in a wide sense, representing any map , where I is a real interval and is a real Banach space or algebra.
WebNov 26, 2016 · Most theorems under real Banach space settings have their twin brothers for complex ones, say, the Hahn-Banach theorem. However, some theorems are not valid in complex Banach spaces, and vice versa. I'm reading the Vol. III of "Nonlinear functional analysis and its applications" by Zeidler. Many theorems contained there assume that … WebIn this paper, we mainly discuss the angle modulus of convexity δXa(ϵ) and the angle modulus of smoothness ρXa(ϵ) in a real normed linear space X, which are closely related to the classical modulus of convexity δX(ϵ) and the modulus of smoothness ρX(ϵ). Some geometric properties of the two moduli were …
