We establish an algebraic version of the classical result that a G-map f between G-complexes which restricts to a homotopy equivalence fH on H-fixed sets for all subgroups H of G is a G-homotopy equivalence. This is used to give an alternative proof of a theorem of Bouc. We also include a number of illustrations and applications.

The distribution of quality characteristic of a product is usually assumed to be known. In some situation, the quality characteristic of a product cannot be measured directly. It needs to be measured by controlling another factor. Wen and Mergen (1999) presented a method for determining the optimum process mean in order to minimize the expected total loss of a product. However, they have not co...

This survey paper gives an overview of the recent classification of all endopermutation kP -modules, where P is a finite p-group and k is a field of characteristic p. It is an expanded version of two talks given in April 2005 during a special workshop on endo-permutation modules, organized within the program of the Bernoulli Centre of EPFL. The classification of endo-permutation modules was com...
