Abstract: Borisov and Gunnels observed in 2001 that certain linear relations between products of two holomorphic weight 1 Eisenstein series had the same structure as the relations between periods of modular forms. We give a conceptual reason for this and for similar phenomena in all weights. This involves an unconventional way of expanding the Rankin-Selberg convolution of a cusp form with an Eisenstein series. (Joint with Kamal Khuri-Makdisi).
