E-raamat: Non-Kissing Complexes and Tau-Tilting for Gentle Algebras

"We interpret the support -tilting complex of any gentle bound quiver as the non-kissing complex of walks on its blossoming quiver. Particularly relevant examples were previously studied for quivers defined by a subset of the grid or by a dissection of apolygon. We then focus on the case when the non-kissing complex is finite. We show that the graph of increasing flips on its facets is the Hasse diagram of a congruence-uniform lattice. Finally, we study its g-vector fan and prove that it is the normal fan of a non-kissing associahedron"--

Palu, Pilaud, and Plamondon interpret the support t-tilting complex of any gentle bound quiver as the non-kissing complex of walks on its blossoming quiver. Having previously studied quivers defined by a subset of the grid or by a dissection of a polygon, here they focus on the case when the non-kissing complex is finite. They show that the graph of increasing flips on its facets is the Hasse diagram of a congruence-uniform lattice. Annotation ©2022 Ringgold, Inc., Portland, OR (protoview.com)
