Abstract
We rederive the equation for vertical hydrodynamical equilibrium of stationary thin and slim accretion disks in the Kerr spacetime. All the previous derivations have been unsatisfactory, yielding unphysical singularities. Our equation is nonsingular, more general, and simpler than those previously derived.Keywords
