Abstract
The paper uses the formalism of tensor products in order to deal with the problem of simultaneous
stabilizability of a family of linear control systems by means of Lyapunov functions which are homoge-
neous polynomial forms. While the feedback synthesis seems to be nonconvex, the simultaneous stability
by means of homogeneous polynomial forms of the uncontrollable modes yields (convex) necessary but
not sufficient conditions for simultaneous stabilizability.
I. INTRODUCTION
For a linear system without inputs, an -time tensor product of its n-dimensional state space yields
a polynomial system homogeneous of degree . See [5] for a survey of the use of tensor products
