Addition laws on elliptic curves in arbitrary characteristics
The paper deals with the possibility of describing the addition law on a projective elliptic curve via bihomogeneous polynomials of preassigned bidegree. The authors prove a general result, then make explicit computations for the Tate-Weierstraß model and consider degenerate cases.
