Mekler's construction and generalized stability

Submission date: 15 August 2017


Mekler's construction gives an interpretation of any structure in a finite relational language in a pure group (nilpotent of class 2 and exponent p > 2, but not finitely generated in general). Even though this construction is not a bi-interpretation, it is known to preserve some model-theoretic tameness properties of the original structure including stability and simplicity. We demonstrate further that k-dependence of the theory is preserved, for all k in N, and that NTP2 is preserved. We apply this result to obtain first examples of strictly k-dependent pure groups.
