摘要
In this paper, we consider the well-posedness issue for the density-dependent incompressible viscoelastic fluids of the Oldroyd model for the ideal case in space dimension greater than 2. We obtain the local well-posedness of this model under the assumption that the initial density is bounded away from zero in the critical Besov spaces by means of the Littlewood-Paley theory and Bony's paradifferential calculus. In particular, we obtain a Beale-Kato-Majida-type regularity criterion.
