SUMMARY:On indefinite damping and gyroscopic stabilization - Tobias Damm\,

DESCRIPTION:We consider linear vibrational systems with positive definite 
 stiffness matrix $K$ and indefinite damping matrix $D$. For the system to 
 be stabilizable by gyroscopic forces it is necessary that both the trace o
 f $D$ and the trace of $K^{-1}D$ is negative. In the present talk we discu
 ss sufficiency of this condition. As tools we derive results on hollow mat
 rices and symplectic transformations.
