Abstract : In recent years many of the methods used to investigate stability of lumped parameter systems have been extended to study the stability of distributed systems. In this short paper the authors employ an extension of the circle-criterion to Hilbert space-valued systems, as well as some rather sophisticated results on elliptic boundary value problems. The stimulus for the approach is the desire to have calculable criteria for stability. (Author)
