Investigations about linear stability of nonconservative systems with non symmetric stiness matrices lead to linear algebra results that are unusual in mechanics. It may also lead to original linear algebra developments. It is illustrated about linear divergence stability when adding kinematic constraints on the nonconservative system. The original concept of m-positive definite matrices is proposed, the main result is given and some mathematical open problems are suggested.
Keywords: nonconservative systems; kinematic constraints
