Applied Functional Analysis 3

Here is a revised and enlarged version of this useful reference text on functional analysis and its application to problems of system optimi- zation: filtering and control. Written for the needs of engineers and scientists, the emphasis is on providing the most useful material as opposed to the most general. It covers such topics as Volterra and Hilbert-Schmidt operators; convex programming in a Hilbert space; semigroup theoretic models for systems governed by P. D. E., con- trollability, and observability of infinite dimensional systems; and stochastic (Kalman) filtering and control via rigorous white noise the- ory, including (asymptotic) steady state theory for infinite dimen- sional systems. It also includes, for instance, the kind of background theory needed for rigorous treatment of active stabilization of flex- ible flight structures.

Their Generation Changed The Calculus From A Method Of Solving Problems To A Collection Of Theorems, Based On Precise Definitions, About Limits, Continuity, Series, Derivatives, And Integrals. The Book Shows How Cauchy Reshaped Inherited 18th-century Concepts To Create An Approach To Rigor That We Still Accept Today. In So Doing, The Origins Of Cauchy's Rigorous Calculus Provides Fresh Insights And A New Perspective On The Foundations Of Analysis.
