## Abstract

top
Let $𝕂$ be an algebraically closed field. Consider a finite dimensional monomial relations algebra $\Lambda =𝕂\Gamma /\phantom{𝕂\Gamma I}\phantom{\rule{0.0pt}{0ex}}I$ of finite global dimension, where Γ is a quiver and I an admissible ideal generated by a set of paths from the path algebra $𝕂\Gamma$ . There are many modules over Λ which may be represented graphically by a tree with respect to a top element, of which the indecomposable projectives are the most natural example. These trees possess branches which correspond to right subpaths of cycles in the quiver. A pattern in the syzygies of a specific factor module of the corresponding indecomposable projective module is found, allowing us to conclude that the square of any cycle must lie in the ideal I.
