Commutative algebra and graph theory are two vibrant areas of mathematics that have grown increasingly interrelated. At this interface, algebraic methods are applied to study combinatorial structures, ...
Graphs are everywhere. In discrete mathematics, they are structures that show the connections between points, much like a ...
