摘要：
L. A. Rubel's universal differential equation (1981, Bull. AMS 4, 345-349) corresponds to an algebraic polynomial in four variables of degree seven. A simpler universal differential equation is found where the attached polynomial is homogeneous of degree six. We investigate complex-valued C-(infinity)-solutions of this differential equation, whose imaginary parts approximate arbitrary continuous functions on R. (C) 2000 Academic Press.
