    Daniel Schultz, TU Kaiserslautern: Modular Equations in Two Variables

    By adding certain equianharmonic elliptic sigma functions to the
    coefficients of the Borwein cubic theta functions, an interesting set of six
    two-variable theta functions may be derived. These theta functions
    invert a special case of Appell’s hypergeometric function and
    satisfy several identities akin to those satisfied by the Borwein
    cubic theta functions. In this talk I will discuss the modular
    properties of these functions as well as the computation of their
    modular equations, which turn out to be algebraic surfaces. An
    application of these results is a new two-parameter family X^9 −
    3*X^8 + 4*t*X^6 − 6*s*X^5 − 6*s*X^4 + 4*s*t*X^3 − 3*s^2*X + s^2 = 0
    of solvable nonic equations.
