FilledSmallSquare ModularLambda[] gives the modular lambda elliptic function .

FilledSmallSquare Mathematical function (see Section A.3.10).

FilledSmallSquare ModularLambda is defined only in the upper half of the complex plane. It is not defined for real .

FilledSmallSquare The argument is the ratio of Weierstrass half-periods .

FilledSmallSquare ModularLambda gives the parameter for elliptic functions in terms of according to .

FilledSmallSquare ModularLambda is related to EllipticTheta by where the nome is given by .

FilledSmallSquare is invariant under any combination of the modular transformations and .
