摘要🍃：The theory of theta functions was regarded as one of the most significant accomplishments of the 19 century by C. L. Siegel, its generalization was suggested in a paper of A. Weil. The dimension of space of generalized theta functions was predicted by Comformal Field Theory.

In this talk, we try to explain an (finite dimensional) approach inspired by the above prediction, and I will start the story from abel's integral.
