Embeddings of Some Weightedfunction
نویسنده
چکیده
In this survey we summarise recent results concerning compact embeddings of some weighted function spaces of type B s p;q and F s p;q on R n. We study the asymptotic behaviour of their entropy and approximation numbers. We give some motivation how to apply results of this type in spectral theory. This survey provides a uniied approach of recent outcomes (which have mostly been published before) and marks some present`state of the art' in this eld of research.

متن کاملLabeling Subgraph Embeddings and Cordiality of Graphs
Let $G$ be a graph with vertex set $V(G)$ and edge set $E(G)$, a vertex labeling $f : V(G)rightarrow mathbb{Z}_2$ induces an edge labeling $ f^{+} : E(G)rightarrow mathbb{Z}_2$ defined by $f^{+}(xy) = f(x) + f(y)$, for each edge $ xyin E(G)$. For each $i in mathbb{Z}_2$, let $ v_{f}(i)=|{u in V(G) : f(u) = i}|$ and $e_{f^+}(i)=|{xyin E(G) : f^{+}(xy) = i}|$. A vertex labeling $f$ of a graph $G...
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 کاملConstraining Word Embeddings by Prior Knowledge - Application to Medical Information Retrieval
Word embedding has been used in many NLP tasks and showed some capability to capture semantic features. It has also been used in several recent studies in IR. However, word embeddings trained in unsupervised manner may fail to capture some of the semantic relations in a specific area (e.g. healthcare). In this paper, we leverage the existing knowledge (word relations) in the medical domain to c...
متن کاملOrder dense injectivity of $S$-posets
In this paper, the notion of injectivity with respect to order dense embeddings in the category of $S$-posets, posets with a monotone action of a pomonoid $S$ on them, is studied. We give a criterion, like the Baer condition for injectivity of modules, or Skornjakov criterion for injectivity of $S$-sets, for the order dense injectivity. Also, we consider such injectivit...
