โฆ Synopsis
As is well known, the finite distributions on Rn form an algebra t 5 ' with respect to the convolution-product ; DIRAC'S measure 6 is the unit of this algebra.
We propose to determine the invertible elements in this algebra.
The algebra &"(*) is isomorphic to the algebra &(a') of the continuous linear operators A : B ' 4 B ' of the distribution-space B', which commute with all translations. Therefore the knowledge of the invertible S E 8" leads to the invertible operators A โฌ &(a'). It turns out, that these are exactly the translations and the non-zero multiples of them.

We prove various results about sharply n-transitive sets of homeomorphisms of ``nice'' topological spaces like the real line and the circle. Our main results concern sharply 3-transitive sets G of homeomorphisms of the circle to itself. If G=G &1 , then G contains a real hyperbolic part (a set of in
