In a Bourbaki seminary note, La Théorie des Fonctions Thêta, A. Weil has discussed two fundamental theorems of the general theory of Theta functions. The first, due to H. Poincaré, was proved very skilfully in the note by means of harmonic integrals on a torus and the second, due to Frobenius, was treated by the systematic use of the notion of analytic structure.

4) We mean by a non-degenerate divisor X a divisor such that Xt—X∽O for only finite number of points t.

5) Z≡0 means that Zt—Z∽0 for all points t. We call such a divisor Z algebraically equivalent to zero.

9) Let ℬ0be the ring generated by Then ℬ0is an algebra of type S. Therefore ℬ0is semi-simple. This shows that there is a non-singular matrix with Iadic element F such that F—1M1(β)F is diagonal for every β∈ℬ0.
