Title: An Introduction to 2-Groups
Speaker: Narthana Epa (Melbourne)
Abstract: 2-Groups are categorification of groups, that is a category which has some attributes of a group. In a 2-group, the multiplication map is a bifunctor, while the inverses and the associativity law may only be defined up to isomorphism. I will discuss a classification for 2-groups where equality does hold for the inverses and associativity, known as special 2-groups. Finally, I will briefly discuss the example of a special 2-group that I constructed in my thesis.
