Abstract
The Drinfeld upper half-planes play the role of symmetric spaces in the -adic analytic world. We find the automorphism group of a product of such spaces, where each may be defined over a different field. We deduce a rigidity theorem for quotients of such products by discrete and torsion free groups.
