Webb7 okt. 2024 · This thesis deals with one of the very basics of theoretical physics: computing observable quantities. In the language commonly used to describe the subatomic world, gauge theories, this problem is far from trivial as the observables are expressed in terms of infinite-dimensional integrals. This holds true even in supersymmetric gauge theories, … WebbAbout this book Gives an account of Liouville's theory of integration in finite terms -- his determination of the form which the integral of an algebraic function must have when the integral can be expressed with the operations of elementary mathematical analysis, carried out a finite number of times -- and the work of some of his followers.
