Abstract

Let A=kQ/IA={\rm \mathbb{k}}Q/\mathcal{I} be a gentle algebra. We provide a bijection between non-projective indecomposable Gorenstein projective modules over AA and special recollements induced by an arrow aa on any full-relational oriented cycle C\mathscr{C}, which satisfies some interesting properties, for example, the tensor functor AA/AεA-\otimes_A A/A\varepsilon A sends Gorenstein projective module aAaA to an indecomposable projective A/AεAA/A\varepsilon A-module; and AA/AεA-\otimes_A A/A\varepsilon A preserves Gorenstein projective objects if any two full-relational oriented cycles do not have common vertex.
