algebra to count walks in graphs. Conversely, it is sometimes possible to count the walks by combinatorial reasoning and use the resulting formula to determine the eigenvalues of G.

Thus Kp has pvertices ...Combinatorial commutative algebra is a relatively new, rapidly developing mathematical discipline.

Abstract. Combinatorial algebraic geometry comprises the parts of algebraic geometry where basic geometric phenomena can be described with combinatorial data, and where combinatorial methods are essential for further progress. Research in combinatorial algebraic geometry utilizes combinatorial techniques to answer questions about geometry.Combinatorics is an area of mathematics primarily concerned with counting, both as a means and an end in obtaining results, and certain properties of finite structures. It is closely related to many other areas of mathematics and has many applications ranging from logic to statistical physics and from evolutionary biology to computer science .Combinatorics.
