In the most extensive paper from the May 2008 workshop, three Japanese mathematicians classify squarefree monomial ideals of deviation two in a polynomial ring S in terms of hypergraphs, and prove that the arithmetical rank of an ideal I is equal to the projective dimension of S/I. Topics of the remaining 11 papers include minimal free resolutions of lexsegment ideals, tangent cones of numerical semigroup rings, topological Cohen-Macaulay criteria for monomial ideals, and the type of the base ring associated to a transversal polymatroid.
