Abstract: This paper examines a system of partial differential equations describing dislocation dynamics in a crystalline solid. In particular we consider dynamics linearized about a state of zero stress and use linear semigroup theory to establish existence, uniqueness, and time asymptotic behavior of the linear system.

This paper is dedicated to our friend Costas Dafermos on the occasion of his 80th birthday.
