Evaluation of Some Integrals Following from , the Constant of the Asymptotic Expansion of , Originating from Physics (QED)
W. Dittrich
Comparison of three different regularization methods of calculating the one-loop effective Heisenberg-Euler Lagrangian of quantum electro-dynamics (QED) is employed to derive some…
On Dirichlet's Derivation of the Ellipsoid Potential
W. Dittrich
Newton's potential of a massive homogeneous ellipsoid is derived via Dirichlet's discontinuous factor. At first we review part of Dirichlet's work in an English translation of the…
Classical and Quantum Mechanics with Lie Brackets and Pseudocanonical Transformations
W. Dittrich
We emphasize the usefulness of the Lie brackets in the context of classical and quantum mechanics. By way of examples we show that many dynamical systems, especially the ones with…
On Riemann's Paper, "On the Number of Primes Less Than a Given Magnitude"
W. Dittrich
This paper is devoted to one of the members of the Göttingen triumvirate, Gauß, Dirichlet and Riemann. It is the latter to whom I wish to pay tribute, and especially to his world-f…
On Tomonaga's Theory of Split-Anode Magnetrons
Walter Dittrich
This article is meant to formulate the equations of motion of an electron in a cavity magnetron using action-angle variables. This means following the electron's path on its way fr…
The Cofounder of Quantum Field Theory: Pascual Jordan
Walter Dittrich
A comparative study is undertaken that brings to light the two different methods of how to treat the many-body problem in quantum field theory. The two main researchers who publish…
