Zipper unfoldings of polyhedral complexes
We explore which polyhedra and polyhedral complexes can be formed by folding up a planar polygonal region and fastening it with one zipper. Expand
The Generalized Nagell–Ljunggren Problem: Powers with Repetitive Representations
We consider a natural generalization of the Nagell–Ljunggren equation to the case where the qth power of an integer y, for q ⩾ 2, has a base-b representation that consists of a length-ℓ block of digits repeated n times. Expand
