Homogeneous Function

A function which satisfies

$$f(tx,ty)=t^nf(x,y)$$

for a fixed $n$. Means, the Weierstraß Elliptic Function, and Triangle Center Functions are homogeneous functions. A transformation of the variables of a Tensor changes the Tensor into another whose components are linear homogeneous functions of the components of the original Tensor.
