Migratory Alimony: A Constitutional Dilemma in the Exercise of In Personam Jurisdiction

Obstacles to obtaining binding determinations of domicile often block the personal jurisdiction required for alimony adjudication. A way out of the impasse, Professor Ritz argues, is offered by the mechanism of removing cases to federal courts under the constitutional grant of federal jurisdiction based on diversity of citizenship

The low energy effective Lagrangian for photon interactions in any dimension

The subject of low energy photon-photon scattering is considered in arbitrary dimensional space-time and the interaction is widened to include scattering events involving an arbitrary number of photons. The effective interaction Lagrangian for these processes in QED has been determined in a manifestly invariant form. This generalisation resolves the structure of the weak-field Euler-Heisenberg Lagrangian and indicates that the component invariant functions have coefficients related, not only to the space-time dimension, but also to the coefficients of the Bernoulli polynomial.Comment: In the revised version, the results have been expressed in terms of Bernoulli polynomials instead of generalized zeta functions; they agree for spinor QED with those of Schubert and Schmidt (obtained differently by path integral methods)
