Third Italian Number Theory Meeting

On the canonical height on the endomorphisms ring of a vector space over a global function field

speaker: Valerio Talamanca (Universita' Roma Tre)

abstract: n this talk I will discuss the construction of a canonical height on the endomorphisms ring of a vector space $E$ over a global function field \($k$\). The height constructed satisfies a limit formula, analogous to the formula satisfied by the canonical height attached to an ample line bundle on an abelian variety, with respect to any heights on \($E$\) given by the assignment of a pure adelic vector bundle structure on \($E$\). As a consequence we will construct the canonical height on any \'etale \($k$\)-algebra.
