Abstract
Formula presented A homogeneous curve is one which satisfies a differential equation γ1(t) — (A/t)γ1{t), 0 < t < oo, where A is a nonsingular matrix all of whose eigenvalues have positive real part. An approximately homogeneous curve γ(t) has the form γ1(0 + γ2(0> where γ2(t) is a carefully specified “error”, such that yfp is also restricted for j = 2, n + 1. The approximately homogeneous curves generalize the curves of standard type treated by Stein and Wainger.
