Virasoro blocks and quasimodular forms
We analyse Virasoro blocks in the regime of heavy intermediate exchange (h$_{p}$→ ∞). For the 1-point block on the torus and the 4-point block on the sphere, we show that each order in the large-h$_{p}$ expansion can be written in closed form as polynomials in the Eisenstein series. The appearance o...
