Diagram chasing method
WebIn the ordinary diagram chase, we used elements of sets. We will now replace those elements by arrows in a simple way: Instead of looking at "elements" " " of some object of an abelian category , we look at arrows towards that element; that is, arrows for arbitrary objects of . For "the codomain of an arrow is ", we write , Webat least the Hausdorff distance between the two diagrams. We use diagram-chasing methods from algebraic topology to prove (1) for the Hausdorff distance and approximation by piecewise linear func-tions together with linear interpolation to strengthen (1) from Haus-dorff to bottleneck distance.

WebSep 9, 2015 · There are very few exercises, unlike standard graduate textbooks like Hartshorne, and a lot of the proofs are simplex/diagram chasing, so I decided to skip a lot of the proofs and read the book casually. A big disadvantage to this method is that I don't understand anything at a deep level and I'm only familiar with a few buzzwords.
