   Title: Group actions in algebraic K-theory

   Abstract. Algebraic K-groups are deep invariants of rings,
   which hide beautiful patterns and connections to problems in number
   theory. Lower K-groups have explicit algebraic descriptions, but
   higher algebraic K-groups require sophisticated topological and
   categorical machinery to define, and their introduction by Quillen
   was the culminating point of a long search for a definition that
   would meaningfully generalize the existing definitions of lower
   K-groups. In this talk, I will give a flavor of algebraic K-theory
   and its history, and I will describe current research aimed at
   telling the story in the case when the input has a group action.
