German title
Goodwillie-Kalkül

Contents
Goodwillie calculus is a categorification of ordinary calculus where functions are replaced by
functors. The basic concept is that of n-excisive functor, which is the analogue of a polynomial
function of degree at most n. Under suitable conditions, functors between infinity-categories admit
n-excisive approximations, which together form a Taylor series; functors whose Taylor series
converges are called analytic. Several basic features of calculus, like the chain rule and the
product rule, have counterparts in Goodwillie calculus. The goal of this seminar is to explore these
ideas and phenomena.
