Buan–Marsh conjecture on uniqueness of complete τ-exceptional sequences
Buan–Marsh conjecture. If two complete -exceptional sequences over differ in only one place, then they do not exist; equivalently, the result proved for -tilt…

Hille–Perling tameness conjecture for exceptional toric systems
Let be a rational surface of Picard number . An exceptional toric system is a toric system arising from an exceptional sequence, and it is tame if, for some sequenc…
