abstract = { In this paper we study the existence theorem for solution of the nonlinear degenerate oblique boundary value problems for second order fully nonlinear elliptic equations F(x, u, Du, D&sup2u) = 0 \quad x &#8712 &#937, G(x, u, D, u) = 0, \qquad x &#8712 &#8706&#937 where F (x, z, p, r) satisfies the natural structure conditions, G (x, z, q) satisfies G_q &#8805 0, G_x &#8804 - G_0 < 0 and some structure conditions, vector &#964 is nowhere tangential to &#8706&#937. This result extends the works of Lieberman G. M., Trudinger N. S. [2], Zhu Rujln [1] and Wang Feng [6].},
