Abstract

Nesterenko (Sb. Math. 187:1319–1348, [1996]) proved, among other results, the algebraic independence over ℚ of the numbers π and e π. A very important feature of his proof is a multiplicity estimate for quasi-modular forms associated to SL 2(ℤ) which involves differential properties of certain non-linear differential systems.

The aim of this article is to begin the study of the corresponding properties for Hilbert modular and quasi-modular forms, especially those which are associated with the number field \(\mathbb{Q}(\sqrt{5})\) . We show that the differential structure of these functions has several analogies with the differential structure of the quasi-modular forms associated to SL 2(ℤ).
