Abstract

The article focuses on the gap cohomology group of a tower defined by Dan Talayco. It states that this group is isomorphic to the collection of gaps in the tower modulo the equivalence relation given by two gaps being equivalent if their symmetric difference is not a gap in the tower. It notes that Talayco shows that there is always some tower whose gap cohomology group has size 2.
