1896 Amer. Jrnl. Sociol. 2 258 For all points between the curve and the asymptotes Δ(w;i,j) is non-positive.

1940 Acta Mathematica 80 260 The universal covering space of any space with non-positive curvature is straight.

1968 P. A. P. Moran Introd. Probability Theory vi. 274 It has a right-hand derivative almost everywhere..which must be non-positive and non-decreasing.

1985 Los Angeles Times (Electronic ed.) 8 Sept. One of the charges being made is that the picture shows Chinese (Asians) in an unattractive, non-positive and stereotypical light.

1990 IMA Jrnl. Numerical Anal. 10 584 This definition of the problem includes the case of restricting to nonpositive rather than to nonnegative divided differences.

1993 Spy (N.Y.) June 6/2 In a mass demonstration of nonpositive role modelling, a bank robber temporarily delayed his capture by tossing $10,000 into the street, creating instant traffic gridlock.
