  We represent three generations of students: Bob Glassey, Walter's student
finishing at Brown in 1972, Jack Schaeffer, Bob's student finishing at Indiana
University in 1983, and Steve Pankavich, Jack's student finishing at Carnegie
Mellon in 2005. We have all thrived professionally from our association with
Walter and are delighted to dedicate this note to him on the occasion of his
70th birthday. The problem we study concerns the asymptotic behavior of
solutions to Vlasov equations, an area to which Walter has contributed greatly.
