Abstract
Let V be a finite-dimensional vector-space. A linear mapping ϕ on V is called simple if V(ϕ - 1) is 1-dimensional. Let S be a set of simple bijections on V. We discuss conditions entraining that each element of S is orthogonal (respectively symplectic) under an appropriate symmetric (respectively symplectic) bilinear form on V.
