In mathematics, theta functions are special functions of several complex variables. They show up in many topics, including Abelian varieties, moduli spaces, quadratic forms, and solitons. As Grassmann algebras, they appear in quantum field theory. The most common form of theta function is that occurring in the theory … Se mer There are several closely related functions called Jacobi theta functions, and many different and incompatible systems of notation for them. One Jacobi theta function (named after Carl Gustav Jacob Jacobi) … Se mer Jacobi's identities describe how theta functions transform under the modular group, which is generated by τ ↦ τ + 1 and τ ↦ −1/τ. Equations for the first transform are easily found since adding one to τ in the exponent has the same effect as adding 1/2 to z (n ≡ n Se mer The Jacobi triple product (a special case of the Macdonald identities) tells us that for complex numbers w and q with q < 1 and w ≠ 0 we have Se mer Lemniscatic values Proper credit for most of these results goes to Ramanujan. See Ramanujan's lost notebook and a relevant reference at Euler function. … Se mer The Jacobi theta function defined above is sometimes considered along with three auxiliary theta functions, in which case it is written with a double 0 subscript: Se mer Instead of expressing the Theta functions in terms of z and τ, we may express them in terms of arguments w and the nome q, where w = e and q = … Se mer The Jacobi theta functions have the following integral representations: Se mer NettetIn the last section we relate hto a period integral of a unary theta function of weight 3/2. 1.2 The Mordell integral In this section, we present results of Mordell found in [17] and [18], in a form suitable for the purpose of this chapter. The function hdefined in Definition 1.1 is essentially the function ϕstudied by Mordell: ϕ(x;τ ...
