    Topic: On the algebraic K-theory of double points

    Algebraic K-theory is a very interesting and subtle invariant which shows up in algebra, geometry, and topology. For regular noetherian rings we have several comparison theorems which give us many computational results in these cases, but even for the simplest types singularities the algebraic K-theory remains quite mysterious. In this talk I will review what K-theory is and my use of the recent work of Bhatt, Morrow, Scholze, and others to compute algebraic K-theory of some simple singular rings, such as double points.
