Abstract

Let A A and B B be m m -accretive linear operators in a complex Hilbert space H H with D ( A ) D ( B ) D(A) \subset D(B) . The method of quasi-reversibility is used to obtain a solution to the Sobolev equation ( d / d t ) [ ( I + B ) u ( t ) ] + A u ( t ) = 0 , 0 > t > 1 (d/dt)[(I + B)u(t)] + Au(t) = 0,0 > t > 1 , which approximates a specified final value u ( 1 ) = f u(1) = f . In general, when D ( A ) D ( B ) D(A) \subset D(B) , it is not possible to find a solution which achieves exactly the final value u ( 1 ) = f u(1) = f .
