Title:  Yet another proof of additivity in algebraic K-theory

Abstract:  The so-called additivity theorem is one of the fundamental
results in algebraic K-theory. I will present a shortcut through
Waldhausen's proof of this theorem, using only a minor strengthening
of Quillen's theorem A instead of theorem B. Although unavoidably
technical, this talk will describe the result and focus on the
simplicial techniques involved in its proof.
