Letbe a natural number and letbe an ideal class of an imaginary quadratic number field. Zagier and Gangl constructed-valued invariantswhich they named “the enhanced zeta value”, since the real part of, after being multiplied by a certain elementary factor in terms of a factorial and a power of, equals the partial zeta value. They also constructed the enhanced polylogarithm, a-valued function on the-th Bloch group, and formulated an enhanced conjecture forthat gives a natural lift of the polylogarithm conjecture forto a conjectural equality in. In this article, we define the Shintani L-function of two variables which is naturally regarded as a two-variable analog of the partial zeta function for imaginary quadratic fields. Then we study its analytic properties in order to construct-valued invariants() for a ray classusing the first partial derivative of the Shintani L-function at. From the construction,andare complex conjugate invariants that satisfy $\zeta’(1-m,\mathcal {A})=\Lambda _ {1}(1-m,\mathcal {A})+\Lambda _ {2}(1-m,\mathcal {A}) $. Then we prove the main theorem of this article about the equality between Zagier and Gangl’s enhanced zeta valueand, by explicit calculation of the Fourier expansion of the partial derivative of the Shintani L-function. Finally, we formulate the enhanced conjecture for the ray class invariants, by which we expand Zagier-Gangl’s original conjecture. We also give several numerical examples to verify the correctness of our enhanced conjecture. References
