Families of translations of commutative algebraic groups. (English) Zbl 0657.14026
Abstract: It is shown that for certain compactifications of a connected commutative algebraic group G in \({\mathbb{P}}_ N\) the translation by points g of G can be described completely by quadratic forms in such a way, that the forms depend holomorphically on g. This implies that some zero estimates in transcendence theory are effective.
