متن کامل5 Smooth Free Involution of H C P 3 and Smith Conjecture for Imbeddings of S 3 in S 6
This paper establishes an equivalence between existence of free involutions on HCP 3 and existence of involutions on S with fixed point set an imbedded S, then a family of counterexamples of the Smith conjecture for imbeddings of S in S are given by known result on HCP . In addition, this paper also shows that every smooth homotopy complex projective 3-space admits no orientation preserving smo...
متن کاملCoarse Geometry and P. A. Smith Theory
We define a generalization of the fixed point set, called the bounded fixed set, for a group acting by isometries on a metric space. An analogue of the P. A. Smith theorem is proved for metric spaces of finite asymptotic dimension, which relates the coarse homology of the bounded fixed set to the coarse homology of the total space.
متن کاملOn the "Smith is Huq" Condition in S-Protomodular Categories
We study the so-called “Smith is Huq” condition in the context of Sprotomodular categories: two S-equivalence relations centralise each other if and only if their normalisations commute. We prove that this condition is satisfied by every category of monoids with operations equipped with the class S of Schreier split epimorphisms. Some consequences in terms of characterisation of internal struct...

Grafts of autologous keratinocytes genetically altered to secrete a new gene product are a potential vehicle for gene therapy. T o consider the feasibility of such an approach, w e have examined the ability of keratinocytes to secrete and deliver apolipoprotein E (apoE) to the circulation of mice bearing grafts of h u m a n keratinocytes. The grafted keratinocytes secreted two forms of apoE, an...
