Two mappings related to semi-inner products and their applications in geometry of normed linear spaces

Sever Silvestru Dragomir, Jaromír J. Koliha (2000)

Applications of Mathematics

Similarity:

In this paper we introduce two mappings associated with the lower and upper semi-inner product ( · , · ) i and ( · , · ) s and with semi-inner products [ · , · ] (in the sense of Lumer) which generate the norm of a real normed linear space, and study properties of monotonicity and boundedness of these mappings. We give a refinement of the Schwarz inequality, applications to the Birkhoff orthogonality, to smoothness of normed linear spaces as well as to the characterization of best approximants.

Similarity:

In this paper, the ℱ -Riesz norm for ordered ℱ -bimodules is introduced and characterized in terms of order theoretic and geometric concepts. Using this notion, ℱ -Riesz normed bimodules are introduced and characterized as the inductive limits of matricially Riesz normed spaces.

F. Riesz Theorem

Keiko Narita, Kazuhisa Nakasho, Yasunari Shidama (2017)

Formalized Mathematics

Similarity:

In this article, we formalize in the Mizar system [1, 4] the F. Riesz theorem. In the first section, we defined Mizar functor ClstoCmp, compact topological spaces as closed interval subset of real numbers. Then using the former definition and referring to the article [10] and the article [5], we defined the normed spaces of continuous functions on closed interval subset of real numbers, and defined the normed spaces of bounded functions on closed interval subset of real numbers. We also...
