Asymptotic behaviour of Maxwell fields in higher dimensions

Popis výsledku v původním jazyce

We study the fall-off behaviour of test electromagnetic fields in higher dimensions as one approaches infinity along a congruence of ''expanding'' null geodesics. The considered backgrounds are Einstein spacetimes including, in particular, (asymptotically) flat and (anti-)deSitter spacetimes. Various possible boundary conditions result in different characteristic fall-offs, in which the leading component can be of any algebraic type (N, II or G). In particular, the peeling-off of radiative fields $F=Nr^{1-n/2}+Gr^{-n/2}+ldots$ differs from the standard four-dimensional one (instead it qualitatively resembles the recently determined behaviour of the Weyl tensor in higher dimensions). General $p$-form fields are also briefly discussed. In even $n$ dimensions, the special case $p=n/2$ displays unique properties and peels off in the ''standard way'' as $F=Nr...{1-n/2}+IIr...{-n/2}+ldots$. A few explicit examples are mentioned.
