Solving Systems of Equations of Raising-to-Powers Type

Abstract

We address special cases of the analogues of the exponential algebraic closedness conjecture relative to the exponential maps of semiabelian varieties and to the modular $j$ function. In particular, we show that the graph of the exponential of an abelian variety intersects products of free rotund varieties in which the subvariety of the domain is a sufficiently generic linear subspace, and that the graph of $j$ intersects products of free broad varieties in which the subvariety of the domain is a M\"obius subvariety.
