We show that any lattice-ordered group (/-group) G can be/-embedded into continuously many/-groups 11, which are pairwise elementarily inequivalent both as groups and as lattices with constant e. Our groups Hz can be distinguished by group-theoretical first-order properties which are induced by latt
We construct a special class of noncongruence modular subgroups and curves, analogous in some ways to the usual congruence ones. The subgroups are obtained via the Burau representation, and the associated quotient curves have a natural moduli space interpretation. In fact, they are reduced Hurwitz s
