The Hochschild cohomlogy ring of a self-injective Nakayama algebra is a Batalin-Vilkovisky algebra

Xiuli Bian, Tomohiro Itagaki, Wen Kou +2

Lambre, Zhou and Zimmermann showed that the Hochschild cohomology ring of a Frobenius algebra with semisimple Nakayama automorphism is a Batalin-Vilkovisky algebra. They asked whet…

Formal deformations, cohomology theory and $L_{\infty} [1]$ -structures for differential Lie algebras of arbitrary weight

Weiguo Lyu, Zihao Qi, Jian Yang +1

Generalising a previous work of Jiang and Sheng, a cohomology theory for differential Lie algebras of arbitrary weight is introduced. The underlying $L_{\infty} [1]$ -structure on the…
