Informally speaking, affinization means to convert an algebraic structure with a nullary operation, that is, in which a chosen element plays a special role, into one that has no distinctive elements. The typical example of this procedure is the transition from groups to heaps, and vice versa.

In this course we will attempt to detail this process of affinization for different algebraic structures: groups, rings, Lie and Leibniz algebras.

Planning:

• Affinization of groups: heaps (Speaker: Tomasz Brzeziński)

• Affinization of rings: trusses (Speaker: Tomasz Brzeziński)

• Affinization of Lie algebras: Lie affgebras (Speaker: Krzysztof Radziszewski)

• Affinization of Leibniz algebras: Leibniz affgebras (Speaker: Brais Ramos Pérez)

• Further topics in affinization (Speaker: Tomasz Brzeziński)
