Abstract
Let S-0, ..., S-k be k + 1 similarity classes of matrices over an algebraic ally closed field. This paper gives partial answers to the problems of exis tence (recognition) and uniqueness module simultaneous similarity (rigidity ) of the solutions of the equation A(k) = A(0) + ... +A(k-1), with A(i) is an element of S-i, 0 less than or equal to i less than or equal to k.
