Eine Wanderung durch Rainer Vogt's mathematisches Schaffen (A journey through Rainer Vogt's mathematical work) - MPI-Oberseminar jointly with the Workshop on Homotopy Type Theory -

Rainer Vogt left us last August. With Mike Boardman and Peter
May he invented operads (in particular the little cubes operad) and used
them to conceptualise the notions of homotopy coherence and of homotopy
invariance. Both are fundamental in the study of higher structures. I'll
try to highlight some aspects of Rainer Vogt's work by looking more
closely at several of his articles.
