On Some Embedding Theorems for Inverse Semigroups
A semilattice decomposition of an inverse semigroup has good internal mapping properties. These are used to give natural proofs of some embedding theorems, which were originally proved in a rather artificial way. The reader is referred to [1] for the basic theory of inverse semigroups. In an earlier paper [3] we proved the following embedding result: (1) An E-unitary inverse semigroup is isomor...
متن کاملEmbedding theorems of function classes
In this paper we obtain the necessary and sufficient conditions for embedding results of different function classes. The main result is a criterion for embedding theorems for the socalled generalized Weyl-Nikol’skii class and the generalized Lipschitz class. To define the Weyl-Nikol’skii class, we use the concept of a (λ, β)-derivative, which is a generalization of the derivative in the sense o...
متن کاملSubnormal Embedding Theorems for Groups
In this paper we establish some subnormal embeddings of groups into groups with additional properties; in particular embeddings of countable groups into 2-generated groups with some extra properties. The results obtained are generalizations of theorems of P. Hall, R. Dark, B. Neumann, Hanna Neumann, G. Higman on embeddings of that type. Considering subnormal embeddings of finite groups into fin...
متن کاملCoding Theorems for Reversible Embedding
We consider embedding of messages (data-hiding) into i.i.d. host sequences. As in Fridrich et al. [2002] we focus on the case where reconstruction of the host sequence from the composite sequence is required. We study the balance between embedding rate and embedding distortion. First we determine the distortion-rate region corresponding to this setup. Then we generalize this result in two direc...
متن کاملOn Laplace–Carleson embedding theorems
This paper gives embedding theorems for a very general class of weighted Bergman spaces: the results include a number of classical Carleson embedding theorems as special cases. The little Hankel operators on these Bergman spaces are also considered. Next, a study is made of Carleson embeddings in the right half-plane induced by taking the Laplace transform of functions defined on the positive h...
