Popis: | We show that the reduction mod p of an orthogonal linear representation is orthogonal, and we generalize this fact to representations of algebras with involution.The proofs make an essential use of the notion of " middle lattices ". Comment: paper dedicated to the memory of B. Kostant; second version : misprints corrected; different proof of th.4.2.1; added reference to a paper of Thompson |
