Mathematicians Boij (Royal Institute of Technology, Sweden), Juan C. Migliore (U. of Notre Dame, US), Uwe Nagel (U. of Kentucky), and Fabrizio Zanello (Michigan Technological U.) explore the sequences from a number of perspectives. Among them are characterizing the first half of a pure O-sequence to yield the exact converse to a g-theorem of Hausel, the failing of the unimodality property, the interval conjecture as perhaps the strongest possible structural results, and pure f-vectors as an important special case of pure O-sequences. The treatise is not indexed. Annotation ©2012 Book News, Inc., Portland, OR (booknews.com)
