in 2013, kobayashi proved an analogue of perrin-riou's p-adic gross-zagier formula for supersingular primes. in this talk, we will explain an extension of kobayashi's result to the lambda-adic setting. the main formula is in terms of plus/minus heegner points up the anticyclotomic tower, and its proof, rather than on calculations inspired by the original work of gross-zagier, is via iwasawa theory, based on the connection between heegner points, beilinson-flach elements, and different p-adic l-functions.
