Existence and uniqueness for nonlinear Reynolds equations. (English) Zbl 0624.76090
The pressure distribution in a gas-lubricated bearing is given by the nonlinear Reynolds equation with the boundary value problem $$\nabla \cdot (H^ 3P\nabla P)=\Lambda (HP)_ x$$ in $$\Omega$$, $$P=G$$ on $$\partial \Omega$$. Various results of existence and uniqueness for this equation are presented. Furthermore the system of nonlinear equations arising when elastic deformation of the bearing surfaces is not neglected is discussed.
