Abstract
For the equations λu−dºa(x,u\(\nabla \)u) = f, λu−f = a(x, u,\(\nabla \) u)ºd2u ∀f = Re f ∈ L1 (Rel, dlx) ∩L∞ (Rlx) ∩ C∞ (Ri, dlx) with smooth coefficients in Rl we establish prior bounds on the first and second generalized derivatives of their solutions in the spaces L2p (Rl, dlx), Lp(Rl, dlx), 1 < p < ∞, respectively.
