报告摘要:The Beilinson’s conjecture is one of the most important conjectures in K-theory and establishes very far reaching relations between algebraic K-theory and the value of L-function at integers of projective algebraic variety over number fields. We explain the Beilinson’s conjecture on K2 of curves. Then we construct families of smooth, proper, algebraic curves in characteristic 0, of arbitrary genus g, together with g elements in K2. We show that those elements are in general independent by a limit calculation of the regulator. Working over a number field, we show that in some of those families the elements are integral.
