Tim Randolph talks on  
Control Theory in Banach Spaces.

Abstract: The theory of evolution semigroups is used to provide a framework for studying the stability of general linear control systems. The approach allows one to apply the classical theory of strongly continuous semigroups to time-varying systems in Banach spaces. Properties of stability as determined by time-domain versus frequency-domain techniques are addressed for such systems. What is new is that without Parseval's theorem, the Hilbert space "H-infinity control theory" becomes "Lp-Fourier Multiplier control theory".
