Abstract
V originále
Marginally stable perfect fluid tori with uniform distribution of specific angulat momentum are determined in the Reissner-Nordström-(anti-)de Sitter black-hole and naked singularity spacetimes. Toroidal configurations are allowed only in the spacetimesadmitting existence of stable circular geodesics. The configurations with the equipotential surfaces crossing itself in a cusp allow accretion (inner cusp) of matter from the toroidal configuration.
