摘要

We provide a geometric characterization of tiles in the finite abelian groups \( \mathbb {Z}_{p^n} \times \mathbb {Z}_q \) Z p n × Z q and \( \mathbb {Z}_{p^n} \times \mathbb {Z}_p \) Z p n × Z p , where \( p \) p and \( q \) q are distinct primes, using the concept of a \( p \) p -homogeneous tree, which gives an intuitively visualizable criterion.
