Algebraic types in Zilber's exponential field
arXiv:2405.01399 · doi:10.2140/mt.2025.4.37
Abstract
We characterise the model-theoretic algebraic closure in Zilber's exponential field. A key step involves showing that certain algebraic varieties have finite intersections with certain finite-rank subgroups of the graph of exponentiation. Mordell-Lang for algebraic tori (a theorem of Laurent) plays a central role in our proof.
