Visual Category Theory CoPart 3

<p>This CoPart is a dual complement to Visual Category Theory Brick by Brick Part 3. The original series translated abstract categorical concepts into the language of LEGO® bricks and the CoPart series implement the opposite way of translating brick constructions to the standard diagram language of category theory that should benefit comprehension of definitions. </p><p> </p><p>Since usual categorical diagrams are black and white and occupy less space on paper CoParts include additional color-enhanced diagrams in the spirit of brick constructions when arrow source and target parts use different colors.</p><p> </p><p>These CoParts from CoSeries (named after opposite categories with reversed arrows) keep the same 1-to-1 page correspondence between Parts and CoParts. Page layout is also similar: location of explanatory notes (written using standard mathematical notation) is the same - only bricks are replaced by letters dots and arrows. Therefore this CoSeries can be used independently from the original series or together.</p><p> </p><p>The third CoPart covers adjoint functors diagram shapes and categories cones and cocones limits and colimits pullbacks and pushouts.</p>
