nLab Rainer Vogt

Rainer Vogt (1942–2015) was a mathematician who specialised in homotopy theory.

He received his Ph.D. from the University of Warwick and his thesis advisor was Michael Boardman. He was a a full professor at Osnabrück University in Germany.

He coauthored with Boardman the famous book

This book introduced the notion of weak Kan complexes that was later popularized by André Joyal under the name quasi-categories as a natural basis for the higher category theory of (∞,1)-categories.

An early application of the ideas from that book was in the proof of what is sometimes refereed to as Vogt’s theorem on categories of homotopy coherent maps, between homotopy coherent diagrams. This is briefly discussed at homotopy coherent diagram. It occurs in his paper

which gave a neat explicit construction/description of homotopy limits.
