p-adic Rankin L-series and rational points on CM elliptic curves / M. Bertolini, H. Darmon, K. Prasanna. - In: PACIFIC JOURNAL OF MATHEMATICS. - ISSN 0030-8730. - 260:2(2012), pp. 261-303. [10.2140/pjm.2012.260.261]
Abstract:
This article presents a new proof of a theorem of Karl Rubin relating values of the Katz p-adic L-function of an imaginary quadratic field at certain points outside its range of classical interpolation to the formal group logarithms of rational points on CM elliptic curves. The approach presented here is based on the p-adic Gross-Zagier type formula proved by the three authors in previous work. As opposed to the original proof which relied on a comparison between Heegner points and elliptic units, it only makes use of Heegner points, and leads to a mild strengthening of Rubin's original result. A generalization to the case of modular abelian varieties with complex multiplication is also included.
