Classification conjecture. Trace-equivalence classes of finitely homogeneous structures should correspond to natural model-theoretic properties.
Countability conjecture. There are finitely homogeneous structures up to trace equivalence.
Strong conjecture. For every there are only finitely many finitely homogeneous structures in a -ary language up to trace equivalence.
Let be a free group, and call two pairs of words and -trace equivalent when the corresponding words have equal traces under every repre…
