... The transformation z = ew defines a mapping from the cylinder to the complex plane. On this plane, τ = cst corresponds to circles of radius eτ . Time reversal corresponds to 1/z ∗ , parity to z ∗ . Past infinity is the origin, while future infinity is the complex infinity. Action invariant under con ...

In this paper we use dimensional regularization, deferring to another paper the discussion of other regularizations. A first, basic, result of this paper is that a more thorough tr ...

... In the first chapter, Mechanics, we present the often overemphasized Newtonian approach to mechanics next to the Lagrange and Hamilton formulations. Each of these equivalent representations distinguishes itself by specific advantages: whereas Newton’s approach is most easily accessible using the conce ...
