An extension of the Wedderburn-Artin Theorem
In this paper we give conditions under which a ring is isomorphic to a structural matrix ring over a division ring.
متن کاملAn Extension of Turán's Theorem, Uniqueness and Stability
We determine the maximum number of edges of an n-vertex graph G with the property that none of its r-cliques intersects a fixed set M ⊆ V (G). For (r−1)|M | > n, the (r − 1)-partite Turán graph turns out to be the unique extremal graph. For (r − 1)|M | < n, there is a whole family of extremal graphs, which we describe explicitly. In addition we provide corresponding stability results. Supported...
متن کاملAn Extension of Dilworth's Theorem
We show that any lattice of finite length is isomorphic to the lattice of fully dependent flats of a rank-finite independence space, which is finite if the given lattice is finite. If a suitable submodular function is given on the lattice, the independence space may be so chosen that this submodular function corresponds to the rank function of the independence space under the constructed isomor...
متن کاملAn extension of Wick’s theorem
We propose an extension of a result by Repetowicz et al. (Repetowicz 2004) about Wick’s theorem and its applications: we first show that Wick’s theorem can be extended to the uniform distribution on the sphere and then to the whole class of elliptical distributions. Then, as a special case, we detail this result for distributions that are scale mixtures of Gaussians. Finally, we show that these...
متن کاملAn Extension of Hölder’s Theorem
It is a classical result (essentially due to Hölder) that if Γ is a subgroup of Homeo+(R) such that every nontrivial element acts freely then Γ is Abelian. A natural question to ask is what if every nontrivial element has at most N fixed points where N is a fixed natural number. In the case of N = 1, we do have a complete answer to this question: it has been proved independently by Solodov (not...
