INVARIANT TRIPLE PRODUCTS 2 1 Representations and Integral formulae

Let G = PGL2(R) and let π1, π2, π3 be irreducible admissible smooth representations of G. The the space of G-invariant trilinear forms on π1 ×π2 × π3 is at most one dimensional. This has, in different contexts, been proved by Loke [5], Molchanov [6] and Oksak [7]. In this paper we ask for such a uniqueness result in the context of arbitrary semisimple groups. We show that uniqueness for general...

Se p 20 06 Some remarks on F 1 - schemes

This paper contains a loose collection of remarks on F1-schemes. Etale morphisms and universal coverings are introduced. The relation to toric varieties, at least for integral schemes, is clarified.
