Nuclear dimension of C*-algebras was defined by Winter and Zacharias in a 2010 paper as yet another generalization of topological dimension from spaces to C*-algebras. This one has turned out to be crucial for a lot of deep results in classification and structure of C*-algebras. I will present the definition, after going through necessary background stuff on completely positive maps and order zero maps, which is worth knowing in its own right.
