Betti Sequences over Standard Graded Commutative Algebras with Two Relations,of every .-module . is constant after . steps. We prove that if ., then the Betti sequence of . is determined explicitly by some initial segment of known length, which can be read off a presentation of .. There are three cases, depending on the degrees of the defining relations of . and on whether t

Betti Diagrams with Special Shape,condition for the maximal shifts in the resolution by obvious reasons, and they appear quite frequently in combinatorial contexts. Examples of ideals with special shape are the edge ideal as well as the vertex cover ideal of chordal graphs, whisker graphs and triangulated .-uniform hypergraphs.

The Cayley Trick for Tropical Hypersurfaces with a View Toward Ricardian Economics, systematic study of arrangements of tropical hypersurfaces and, in particular, arrangements of tropical hyperplanes. A recent application to the Ricardian theory of trade from mathematical economics is explored.

How to Flatten a Soccer Ball,p into the plane. For general instances, the boundary of the image is given by two highly singular curves. We determine these curves and show how they demarcate the “flattened soccer ball”. We explore cylindrical algebraic decompositions, by working through concrete examples. Maps onto convex polygo

The Smallest Normal Edge Polytopes with No Regular Unimodular Triangulations,nce of a regular unimodular triangulation of normal edge polytopes of finite graphs. For normal edge polytopes of finite graphs with . vertices, . edges, and no regular unimodular triangulations, we determine the polytope that has the following: (1) the smallest number of vertices (. = 9), (2) the s

Homological Conjectures and Lim Cohen-Macaulay Sequences,ontent for local cohomology modules. We relate both to the problem of proving the direct summand conjecture and other homological conjectures without using almost ring theory and perfectoid space theory, and we also indicate some other open problems whose solution would yield a new proof of the dire
