The leading coefficients at integral arguments of the L-functions of algebraic varieties over number fields seem to be closely related to the global arithmetical geometry of these varieties. A. A. Bejlinson [in J. Sov. Math. 30, 2036-2070 (1985); translation from Itogi Nauki Tekh., Ser. Sovrem. Probl. Mat. 24, 181-238 (1984; Zbl 0588.14013)] has developed a general conjectural formalism which connects the “transcendental” parts of that leading coefficients to so-called regulators, defined by purely algebraic and geometrical means.
The author presents Beilinson conjectures in a way which leads the reader to their statement as directly as possible. A special attention is given to the construction of the Chern class maps from the higher algebraic K- theory into any reasonable cohomology theory, which is a basic ingredient in the definition of the Beilinson regulators.
