Résumé : 

In joint work with Slawomir Kwasik and Reinhardt Schultz from
many years ago, we proved that a finite group acting smoothly on the
three-sphere with an isolated fixed point must have exactly
two such points. The techniques that we used were unusual
for three-dimensional topology, and further consideration
of the underlying ideas suggests that the methods might be
more widely applicable.
