Research Article Functional Inequalities Associated with Jordan-von Neumann-Type Additive Functional Equations
Ulam [1] gave a talk before theMathematics Club of the University ofWisconsin in which he discussed a number of unsolved problems. Among these was the following question concerning the stability of homomorphisms. We are given a group G and a metric group G with metric ρ( , ). Given > 0, does there exist a δ > 0 such that if f :G G satisfies ρ( f (xy), f (x) f (y)) < δ for all x, y G, then a hom...
متن کاملThe James and von Neumann-Jordan type constants and uniform normal structure in Banach spaces
Recently, Takahashi has introduced the James and von Neumann-Jordan type constants. In this paper, we present some sufficient conditions for uniform normal structure and therefore the fixed point property of a Banach space in terms of the James and von Neumann-Jordan type constants and the Ptolemy constant. Our main results of the paper significantly generalize and improve many known results in...
متن کاملA Hierarchy of Von Neumann Inequalities?
The well-known von Neumann inequality for commuting row contractions can be interpreted as saying that the tuple (Mz1 , . . . ,Mzn) on the Drury-Arveson space H 2 n dominates every other commuting row contraction (A1, . . . , An). We show that a similar domination relation exists among certain pairs of “lessor” row contractions (B1, . . . , Bn) and (A1, . . . , An). This hints at a possible hie...
متن کاملFunctional Emergence with Multiple von Neumann Computers
For the spontaneous emergence of the function in the multiagent system through evolution, a designer (man) must refrain from designing agents to excess and make agents behave as freely as possible based upon the rules within themselves. All the designer can do is to implement the system architecture and to specify the environments. The von Neumann machine, which is logically equivalent to the u...
متن کاملJordan-von Neumann Constant for Banaś-fra̧czek Space
For any λ ≥ 1, Rλ is Banaś-Fra̧czek space, the exact value of the Jordan–von Neumann constant CNJ(Rλ) is investigated. By careful calculations, CNJ(Rλ) = 2− 1 λ2 is given.
