Abstract
We study periods and regulators of a certain class of fibrations of varieties whose relative \(H^1\) has multiplication by a number field. Both are written in terms of values of hypergeometric functions \({}_3F_2\) and the former reduces to values of the \(\Gamma \)-function, which provides examples of the conjecture of Gross–Deligne.
