  Multiple polylogarithms and algebraic $K$-theory of fields

  I will explain a connection between multiple polylogarithms and the $E_\infty$-algebra $BGL$. This connection leads to new results in Goncharov’s program, including the Universality Conjecture for number fields, and to new computations of $K$-groups of fields. This is a joint work with I. Sierra and A. Kupers.
