Abstract

In 1984, Dancis proved that any dd-dimensional simplicial manifold is determined by its (d/2+1)(\lfloor d/2 \rfloor + 1)-skeleton. This paper adapts his proof to the setting of cubical complexes that can be embedded into a cube of arbitrary dimension. Under some additional conditions (for example, if the cubical manifold is a sphere), the result can be tightened to the d/2\lceil d/2 \rceil-skeleton when d3d \geq 3.
