Mutations of quivers with 2-cycles
Fang Li, Siyang Liu, Lang Mou +1
We develop a mutation theory for quivers with oriented 2-cycles using a structure called a homotopy, defined as a normal subgroupoid of the quiver's fundamental groupoid. This fram…

Conjugation of reddening sequences and conjugation difference
Siyang Liu, Jie Pan
We describe the conjugation of the reddening sequence according to the formula of -vectors with respect to changing the initial seed. As applications, we extend the Rotation Lem…
