Abstract:
We prove the polynomiality of the bigraded ring Jw,W∗,∗(F4) of weak Jacobi forms for the root system F4 which are invariant
with respect to the corresponding Weyl group. This work is a continuation of a joint article with V. A. Gritsenko, where the structure of the algebras of weak Jacobi forms related to the root systems of Dn type for 2⩽n⩽8 was studied.
This work was supported by International Laboratory for Mirror Symmetry and Automorphic Forms, National Research University Higher School of Economics, under Government grant no. 14.641.31.0001.
