Solutions of equations involving the modular $j$ function

Abstract

Inspired by work done for systems of polynomial exponential equations, we study systems of equations involving the modular jj function. We show general cases in which these systems have solutions, and then we look at certain situations in which the modular Schanuel conjecture implies that these systems have generic solutions. An unconditional result in this direction is proven for certain polynomial equations on jj with algebraic coefficients.
