摘要：
An element a in a Banach algebra A has g-Drazin inverse provided that there exists b subset of A such that b = bab, ab = ba, a-a(2)b. A(qnil). In this paper we give a computational formula for the g-Drazin inverse of operator matrix (E I F 0) which was posed by Campbell in the research on singular differential equations.
