Tagged mapping class groups: Auslander-Reiten translation
Thomas Brüstle, Yu Qiu
We give a geometric realization, the tagged rotation, of the AR-translation on the generalized cluster category associated to a surface with marked points and non-empt…
Frobenius morphisms and stability conditions
Wen Chang, Yu Qiu
We generalize Deng-Du's folding argument, for the bounded derived category of an acyclic quiver , to the finite dimensional derived category o…
C-sortable words as green mutation sequences
Yu Qiu
Let be an acyclic quiver and be a sequence with elements in the vertex set . We describe an induced sequence of simple (backward) tilting in the bounded deriv…
Ext-quivers of hearts of A-type and the orientation of associahedron
Yu Qiu
We classify the Ext-quivers of hearts in the bounded derived category D(A_n) and the finite-dimensional derived category D(Γ_N A_n) of the Calabi-Yau-N Ginzburg algebra D(Γ_N A_n).…
