We study the existence, the uniqueness and the asymptotic behavior of positive solutions of the nonlinear equation

Δv+f(.,v)=0,
in an NTA-cone in ℝ n (n≥3), when a positive Borel measurable function f(.,.) is continuous and non-increasing with respect to the second variable and satisfies a certain condition related to a Kato class.
