Die j-Funktion oder absolute Invariante (j-Invariante, Klein -Invariante) spielt eine wichtige Rolle in der Theorie der elliptischen Funktionen und Modulformen, denn man kann zeigen, dass zwei Gitter genau dann ähnlich sind, wenn ihre j-Invarianten übereinstimmen j-Invariant. The determination of as an algebraic integer in the quadratic field is discussed by Greenhill (1891), Weber (1902), Berwick (1928), Watson (1938), Gross and Zaiger (1985), and Dorman (1988).

Dylan Pentland The j-invariant of an Elliptic Curve 20 May 2018 7 / 1 What is called the j-invariant is an invariant of cubic curves and hence of elliptic curves, partly characterizing them. Over the complex numbers the j-invariant is a modular function on the upper half plane which serves to characterize most of the properties of the moduli stack of elliptic curves in this case

The j invariant Definition The j invariant7 is defined as j(τ) = 1728 g3 2 (τ) ∆(τ), τ ∈ H. Note j istheratiooftwomodularforms of weight 12, hence it is a modular func-tion of weight 0. Since ∆ has a simple zero at infinity but vanishes nowhere else, j has a simple pole at infinity and is holo-morphic on H. Let Γd\H denote the closure of the modu

The j-invariant of an elliptic curve The j-invariant of an elliptic curve with a-ne equation y2 = x3 +px+q is deflned to be j = 1728 4p3 4p3 +27q2: p and q are not uniquely deflned, if we change co-ordinates so that y0 = fi3y and x0 = fi2x for some fi 6= 0, then the new co-e-cients are p0 = fi4p and q0 = fi6q, so we still get the same value of j j ( τ) j (\tau) j (τ) — Modular j-invariant.
