WebFred Galvin, who solved Dinitz problem, combined two well-known math results. We shall introduce and prove these two math results that Galvin used before diving into the main proof. 2.1 Kernel and Directed Graph In order to study Dinitz Problem rigorously, we need to introduce the notion of kernel in directed graph.

The Dinitz conjecture states that, for each « and for every collec-tion of «-element sets S,; , an « x n partial latin square can be found with the (i, j)Xh entry taken from S(J . The analogous statement for (« - 1) x « rectangles is proven here.
