How many functions f:y→x are injective

Webfunctions g: X → R+ and f : Y → R+. Their respective distribution functions Gand F denote G(λ) = µ{g>λ} and F(λ) = ν{f>λ}. The measure spaces will not be assumed to have the same measure (µ(X) and ν(Y) need not be equal). This will not guarantee anymore that R∞ 0 L(x)dσ= 0 for any affine function. In particular, the assumption R∞
