In this paper, conformal motions are studied in plane symmetric static space–times. The general solution of conformal Killing equations and the general form of the conformal Killing vector for these space–times are presented. All possibilities for the existence of conformal motions in these space–times are exhausted.

AbstractWe find multicenter (Majumdar–Papapetrou type) solutions of Eddington-inspired Born–Infeld gravity coupled to electromagnetic fields governed by a Born–Infeld-like Lagrangian. We construct the general solution for an arbitrary number of centers in equilibrium and then discuss the properties of their one-particle configurations, including the existence of bounces and the regularity (geodesic completeness) of these spacetimes. Our method can be used to construct multicenter solutions in other theories of gravity.

Abstract Nonlinear corrections on electromagnetic fields in vacuum have been expected. In this study, we have theoretically considered nonlinear Maxwell’s equations in a one-dimensional cavity for a classical light and external static electromagnetic fields. A general solution for the electromagnetic corrective components including that of a longitudinal standing wave was derived after a linearization. The main purpose is to give a detailed feature of the previously reported resonant behavior [Shibata, Euro. Phys. J. D 74:215 (2020)], such as the effect of external static fields and the polarization fluctuation. These results favor the development of new and effective method for experiment. Graphic abstract

Many years ago (prior to the birth of many SEG members), I published a paper on the electromagnetic fields of a line current in the presence of a homogeneous cylinder (Wait, 1952). Although the general solution presented there was correct, an omission occurred in the reduction to the quasi‐static form. Indeed, Ward and Hohmann (1988) indicated the corresponding expression for [Formula: see text] in my 1952 paper was “wrong” after they had replicated my general derivation. Also, they correctly pointed out that I should not have omitted then n = 0 term in the series expansion for [Formula: see text] in the quasi‐static limit.
