The Dirac and Klein-Gordon equations with equal scalar and vector potentials
We study the three-dimensional Dirac and Klein-Gordon equations with scalar and vector potentials of equal amplitudes as an attempt to present a critique for the interpretation of this class of problems which has recently been accumulating interest. We consider a large class of these problems in which the potentials are noncentral (angulardependent) such that the equations separate completely i...

15 صفحه اولA generalized Petviashvili iteration method for scalar and vector Hamiltonian equations with arbitrary form of nonlinearity
The Petviashvili’s iteration method has been known as a rapidly converging numerical algorithm for obtaining fundamental solitary wave solutions of stationary scalar nonlinear wave equations with power-law nonlinearity: Mu + u = 0, where M is a positive definite self-adjoint operator and p = const. In this paper, we propose a systematic generalization of this method to both scalar and vector Ha...
متن کاملpassivity in waiting for godot and endgame: a psychoanalytic reading
this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...
Dirac operators coupled to vector potentials.
Characteristic classes for the index of the Dirac family [unk](A) are computed in terms of differential forms on the orbit space of vector potentials under gauge transformations. They represent obstructions to the existence of a covariant Dirac propagator. The first obstruction is related to a chiral anomaly.
