Generalized parallel paths method for computing the first Hochschild cohomology group with applications to Brauer graph algebras

Yuming Liu, Bohan Xing

We use algebraic Morse theory to generalize the parallel paths method for computing the first Hochschild cohomology groups. As an application, we describe and compare the Lie struc…

Deformations and Cohomology Theory of Rota-Baxter Systems

Yuming Liu, Kai Wang, Liwen Yin

Inspired by the work of Wang and Zhou [4] for Rota-Baxter algebras, we develop a cohomology theory of Rota-Baxter systems and justify it by interpreting the lower degree cohomology…
