These operations capture the failure of the $E_n$ multiplication to be strictly commutative, and they prove useful for computations. After reviewing the main ideas from May and Cohen\u2019s work, I will discuss a framework to generalize these operations to homology with certain twisted coefficient systems and give a complete classification of twisted operations for $E_{infty}$-algebras. I will also explain computational results that show the existence of new operations for $E_2$-algebras.<\/p>\n<p>Date: Mar 8, 2021<br \/>\nTime: 13:30 UTC+3<\/p>\n<p>This is an online seminar.
