Arithmetic moduli of generalized elliptic curves - ResearchGate
A curve E defined over the field of rational numbers is also defined over the field of real numbers. Therefore, the law of addition (of points with real coordinates) by the tangent and secant method can be applied to E. The explicit formulae show that the sum of two points P and Q with rational coordinates has again rational coordinates, since the line joining P and Q has rational coefficients. This way, one shows that the set of rational points of E forms a subgroup of the group of real po… WebElliptic curve only hash (ECOH) General Designers Daniel R. L.

WebElliptic curves x y P P0 P + P0 x y P 2P An elliptic curve, for our needs, is a smooth curve E of the form y2 = x3 + ax + b. Since degree is 3, line through points P and P0 on E (if P = P0, use tangent at P) has athird pointon E: when y = mx + b, (mx + b)2 = x3 + ax + b has sum of roots equal to m2, so for two known roots r and r0, the third ...
