Fay's trisecant identity
ID: fay-s-trisecant-identity
Fay's trisecant identity is an important result in the theory of elliptic functions and algebraic geometry. It expresses a certain relationship among elliptic functions and their derivatives. In particular, Fay's trisecant identity concerns the trisecant curves associated with an elliptic curve. The identity can be stated in terms of a given elliptic function \( \wp(z) \), which is related to the Weierstrass elliptic functions.
