Current Trends on Monomial and Binomial Ideals

Historically the study of monomial ideals became fashionable after the pioneering work by Richard Stanley in 1975 on the upper bound conjecture for spheres. On the other hand since the early 1990s under the strong influence of Gröbner bases binomial ideals became gradually fashionable in commutative algebra. The last ten years have seen a surge of research work in the study of monomial and binomial ideals. Remarkable developments in for example finite free resolutions syzygies Hilbert functions toric rings as well as cohomological invariants of ordinary powers and symbolic powers of monomial and binomial ideals have been brought forward. The theory of monomial and binomial ideals has many benefits from combinatorics and Göbner bases. Simultaneously monomial and binomial ideals have created new and exciting aspects of combinatorics and Göbner bases. In the present Special Issue particular attention was paid to monomial and binomial ideals arising from combinatorial objects including finite graphs simplicial complexes lattice polytopes and finite partially ordered sets because there is a rich and intimate relationship between algebraic properties and invariants of these classes of ideals and the combinatorial structures of their combinatorial counterparts. This volume gives a brief summary of recent achievements in this area of research. It will stimulate further research that encourages breakthroughs in the theory of monomial and binomial ideals. This volume provides graduate students with fundamental materials in this research area. Furthermore it will help researchers find exciting activities and avenues for further exploration of monomial and binomial ideals.
