[For the entire collection see Zbl 0604.00006.] [For Part III see Acta Math. 155, 261-301 (1985; Zbl 0654.35031).] The existence of the embedded Weingarten surface Y: \(S^ n\to R^{n+1}\) is studied, the principal curvatures \([k_ 1,...,k_ n]\) of which satisfy a relation (1) \(f(-k_ 1,...,-k_ n)=\psi (Y).\) Under the suitable assumptions on f and \(\psi\), the localization of Y as a graph of function v (i.e., \(Y=[x,v(x)]\), \(x=[x_ 1,...,x_ n]\), \(x_{n+1}=v(x))\), transform (1) to the elliptic equation \(G(Dv,D^ 2v)=\psi (x,v)\) (Section 1). It is proved that there exists a \(C^{\infty}\)-surface which solves (1), as well as the fact that any two solutions are endpoints of a one- parameter family of homothetic dilations, all of which are solutions (Theorem 1). The proof of this result is given by the continuity method (Section 2), which is based on a priori estimates, established in Sections 3,4.
