Abstract : During this period the investigator worked on the development of parallel algorithms to be used in the following linear algebra areas --- stability and inertia problems, controllability and observability problems, pole assignment problems, and matrix equations problems (Sylvester, Lyapunov, Riccati, etc). In particular, algorithms have been developed which require O (n log n) steps for solution on O (n 2) processors. Several presentations on these results were given, including a talk at the SIAM Fall Meeting. Three papers have been accepted for publication and several more are in preparation.
