Some properties of marginal automorphisms of groups
AbstractLet W be a non-empty subset of a free group. The automorphism of a group G is said to be a marginal automorphism, if for all x in G,x^−1alpha(x) in W^*(G), where W^*(G) is the marginal subgroup of G.In this paper, we give necessary and sufficient condition for a purelynon-abelian p-group G, such that the set of all marginal automorphismsof G forms an elementary abelian p-group.
متن کاملWeakly Reflective Submanifolds and Austere Submanifolds
We introduce the notion of a weakly reflective submanifold, which is an austere submanifold with a certain global condition, and study its fundamental properties. Using these, we determine weakly reflective orbits and austere orbits of s-representations.
متن کاملDeformations of Calibrated Submanifolds
Assuming the ambient manifold is KK ahler, the theory of complex sub-manifolds can be placed in the more general context of calibrated submanifolds, see HL]. It is therefore natural to try to extend some of the many results in complex geometry to the other calibrated geometries of HL]. In particular, the question of deformability of calibrated submanifolds is addressed here (analogous to Kodair...
متن کاملAveraging of isotropic submanifolds
We will give a construction to obtain canonically an “isotropic average“ of given C close isotropic submanifolds of a Kähler manifold. The isotropic average will be C close to the given submanifolds. The construction relies on an averaging procedure by Weinstein and on “Moser’s trick”.
متن کاملTranscendental submanifolds of Rn
In this paper we show how the restriction of the complex algebraic cycles to real part of a complex algebraic set îs related to the real algebraic cycles of the real part As a corollary we give examples of smooth submanifolds of a Euchdean space which can not be isotoped to real parts of complex nonsingular subvaneties in the corresponding projective space Algebraic numbers are dense in R. The ...
