An important property of homogeneous functions is given by Euler’s Theorem. 3.
In mathematics, a homogeneous function is a function of several variables such that, if all its arguments are multiplied by a scalar, then its value is multiplied by some power of this scalar, called the degree of homogeneity, or simply the degree; that is, if k is an integer, a function f of n variables is homogeneous of … Meer weergeven The concept of a homogeneous function was originally introduced for functions of several real variables.

According to this answer, a system that is additive is also linear, and in consequence it's also homogeneous. Assuming that answer is correct (I haven't verified it myself, but I tend to believe it is), then the answer to your question is no, there are no additive systems that are not homogeneous. – MBaz.

A clustering result satisfies homogeneity if all of its clusters contain only data points which are members of a single class. This metric is independent of the absolute values of the labels: a permutation of the class or cluster label values won’t change the score value in any way. culligan of san antonio txWebBut this makes a homothetic function a monotonic transformation of a homogeneous function.
