The c4-tilting finiteness conjecture for symmetric algebras
The c4-tilting finiteness conjecture for symmetric algebras
Let be a finite-dimensional symmetric algebra. The algebra is -tilting finite if it has only finitely many isomorphism classes of support -tilting modules, and it is tilting-discrete if it has only finitely many tilting complexes of each length. The -tilting finiteness conjecture. Any -tilting finite symmetric algebra is tilting-discrete.
This conjecture concerns the relationship between finiteness of support -tilting modules and finiteness of tilting complexes for symmetric algebras. The paper states that it is false and provides a counterexample.
