Title: Kontsevich and Buchstaber polynomials, multiplication kernels and differential operators of the Calabi-Yau type

Abstract: We are discussing several recent results of ongoing work (in collaboration with I. Gayur and D. By Van Straten and with V. Buchstaber and I. Gayur) about interesting properties of multiplicative generalized Bessel kernels, which include the well-known Clausen and Sonin-Gegenbauer formulas, examples of Kontsevich discriminant locus polynomials given as addition laws for special two-valued formal groups (Buchstaber-Novikov-Veselov), as well as the connection with "period functions" solving some Picard-Fuchs-type equations for the Calabi-Yau cases and related to analogues of Landau-Ginzburg superpotentials.
