Derivations and bounded nilpotence index
We construct a nil ring R which has bounded index of nilpotence 2, is Wedderburn radical, and is commutative, and which also has a derivation δ for which the differential polynomial ring R[x; δ] is not even prime radical. This example gives a strong barrier to lifting certain radical properties from rings to differential polynomial rings. It also demarcates the strength of recent results about ...
متن کاملOn Bounded Analytic Functions
The objective of this paper is to give an alternative derivation of results on bounded analytic functions recently obtained by Ahlfors [l] and Garabedian [2].1 While it is admitted that the main idea to be used is more in the nature of a lucky guess than of a method, it will be found that the gain in brevity and simplicity of the argument is considerable. As a by-product, we shall also obtain a...
متن کاملon the structure and properties of lower bounded analytic frames
algebraic frames are generalizations of fourier transforms on locally compact abelian groups in the sense that the family of vectors forming the frame are replaced by a family of unbounded linear functionals. the paper studies the indexing measure space of the algebraic frames; as the investigation narrows down to the class of lower semiframes, more relations are revealed between the discret...
متن کاملOn Computationally Bounded Adverserial Capacity
The main reason behind the complexity of codingdecoding scheme is the randomness in the source or channel noise. We model source or channel noise as pseudo-random to study the limitation of coding-decoding schemes in the presence of an adversary. In this adverserial model, we characterize the limitations of computationally bounded source and channel coding-decoding schemes in terms of classical...
متن کاملBounded Analytic Functions
If D is a domain in the complex s-plane, then the family B=B(D) of bounded analytic functions in D is defined as consisting of those analytic functions ƒ(z) which are regular and single-valued in D and which satisfy the inequality \f(z) | < 1 at all points of D. The classical investigations of the family B(D) were restricted to the case in which D is a simply-connected domain. In fact, D was ge...
