Simplicity of Certain Groups of Diffeomorphisms
D. Epstein has shown [1] that for quite general groups of homeomorphisms, the commutator subgroup is simple. In particular, let M be a manifold. (In this note, we assume all manifolds are finite dimensional, Hausdorff, class C, and have a countable basis for their topology.) By a C r + mapping (resp. diffeomorphism) we mean a C mapping (resp. diffeomorphism) whose rth derivative is Lipschitz. L...
متن کاملSimplicity of the Reduced C-algebras of Certain Coxeter Groups
Let (G, S) be a finitely generated Coxeter group, such that the Coxeter system is indecomposable and the canonical bilinear form is indefinite but non-degenerate. We show that the reduced C∗-algebra of G is simple with unique normalised trace. For an arbitrary finitely generated Coxeter group we prove the validity of a Haagerup inequality: There exist constants C > 0 and Λ ∈ N such that for a f...
متن کاملThe Simplicity of Certain Nonassociative
Introduction. Let V be an additively written elementary £-group of order pn, where w>l, and let (u, v), yp(u, v) he two alternate biadditive functions defined on V and with values in a field K of characteristic p. Let & be a fixed nonzero element in V, and assume that the following two conditions are satisfied: (0.1) If a, P are nonzero elements in K then a<p(u, v) +P\f/(u, v)=0 lor all v im...
متن کاملDigital cohomology groups of certain minimal surfaces
In this study, we compute simplicial cohomology groups with different coefficients of a connected sum of certain minimal simple surfaces by using the universal coefficient theorem for cohomology groups. The method used in this paper is a different way to compute digital cohomology groups of minimal simple surfaces. We also prove some theorems related to degree properties of a map on digital sph...
متن کاملSimplicity of some automorphism groups
a r t i c l e i n f o a b s t r a c t Let M be a countably infinite first order relational structure which is homogeneous in the sense of Fraïssé. We show, under the assumption that the class of finite substructures of M has the free amalgamation property, along with the assumption that Aut(M) is transitive on M but not equal to Sym(M), that Aut(M) is a simple group. This generalises results of...
