Title: On one amazing formula binding two branches of mathematics


Abstract: Gelfand's spectral radius formula, relating the purely algebraic concept of the spectrum of an element of a complex Banach algebra to the analytic entities of limit and norm, can be rightfully considered a vivid revelation of the intrinsic connection between the two branches of mathematics: algebra and analysis. We are going to consider a traditional proof of this fundamental result based on the generalization of Liouville's theorem in complex function theory to vector-valued functions and see how the formula works within the familiar framework of linear algebra and calculus.
