A simple example of a commutative diagram using TikZ, short and readable. It has been posted as answer to the question http://tex.stackexchange.com/q/45741/213 of Elias. A matrix is used for positioning the main nodes Arrows are drawn as edges, between the… Continue Reading →

In graph theory, models and drawings often consists mostly of vertices, edges, and labels. So, it may be possible, to use a simpler language for generating a diagram of a graph. The tkz-graph package offers a convenient interface. The code… Continue Reading →

A submatrix within a matrix should be highlightened. Instead of simply drawing a rectangle, we can use TikZ for producing a rectangle node, using the fit library for fitting the desired area, defining a style for the highlighted node, so… Continue Reading →

http://texblog.net/latex-archive/maths/pgf-tikz-commutative-diagram/ The chains library is very useful for writing exact sequences. Yet there’s no feature for labeling the edges of a chain. Besides arrows, we might need to write symbols for maps over, under, or just next to it. This… Continue Reading →
