✦ Synopsis


Let V be a finite-dimensional vector space over a number field. In this paper we prove a limit formula for heights on the endomorphism ring of V, which can be considered as the analogue for both the Gelfand Beurling formula for the spectral radius on a Banach algebra and Tate's averaging procedure for constructing canonical heights on abelian varieties. We also prove a version of Northcott's finiteness theorem.
