Regulators of $$K_2$$ K 2 of hypergeometric fibrations

摘要

We describe Beilinson regulators of hypergeometric fibrations in terms of generalized hypergeometric functions. Employing a formula of Rogers and Zudilin, we obtain the comparison of the regulator with the special value of L function of a certain elliptic curve. This is a new approach toward the Beilinson conjecture.
