Jul 31, 2012 at 4:14 comment added Philippe Gaucher It is a shortcut for denoting the map $\mathcal{M}(Y,T)/\simeq \rightarrow \mathcal{M}(X,T)/\simeq$ if $f:X\rightarrow Y$.
Jul 29, 2012 at 17:00 comment added Konrad Voelkel I haven't seen the notation M(f,T) before. What kind of object is it? I thought it should be the set of all commutative diagrams made of f: X -> Y and some X -> T and Y -> T.. but then it doesn't make much sense to me. Would you mind to explain this a little bit?
