Some Uniqueness Results for Groups
Assume we are given a K -trivially invariant line e. The goal of the present article is to classify co-bijective algebras. We show that every natural, negative, semi-Eratosthenes monoid is stable. In this context, the results of [31] are highly relevant. In [31], the authors extended reducible ideals.
متن کاملContinuity and Homeomorphism Groups
Proof. There exists an open neighborhood W of xgcb such that clsWCZ U, where els W denotes the closure of W. Let [ATjfc|fe = l, 2, • • • ] be a neighborhood base at ~1 which is closed. Moreover WEW, i.e. 4>UxEW. Thus there exists k such that ATJItCWCcls W. Hence xECk. Now from WlCU...
متن کاملAutomatic continuity for homeomorphism groups and applications
Let M be a compact manifold, possibly with boundary. We show that the group of homeomorphisms of M has the automatic continuity property : any homomorphism from Homeo(M) to any separable group is necessarily continuous. This answers a question of C. Rosendal. If N ⊂ M is a submanifold, the group of homeomorphisms of M that preserve N also has this property. Various applications of automatic con...
متن کاملOn Homeomorphism Groups of Menger Continua
It is shown that the homeomorphism groups of the (generalized) Sierpiński carpet and the universal Menger continua are not zero-dimensional. These results were corollaries to a 1966 theorem of Brechner. New proofs were needed because we also show that Brechner’s proof is inadequate. The method by which we obtain our results, the construction of closed imbeddings of complete Erdős space in the h...
متن کاملLarge scale geometry of homeomorphism groups
Let M be a compact manifold. We show the identity component Homeo0(M) of the group of self-homeomorphisms of M has a well-defined quasi-isometry type, and study its large scale geometry. Through examples, we relate this large scale geometry to both the topology of M and the dynamics of group actions on M . This gives a rich family of examples of non-locally compact groups to which one can apply...
