Here $H(\\mathbf r)$ is the so-called \"standard height\" of the rational point $\\mathbf r$. In this paper the authors ask: What changes if we replace the standard height function by a different one? As it turns out, this change leads to dramatic differences from the classical theory and requires the development of new methods.
