This article is an expository account of the theory of twisted commutative algebras, which simply put, can be thought of as a theory for handling commutative algebras with large groups of linear symmetries. Examples include the coordinate rings of determinantal varieties, Segre– Veronese embeddings, and Grassmannians. The article is meant to serve as a gentle introduction to the papers of the t...

These notes will give some very basic definitions and results from model theory. They contain many examples, and in particular discuss extensively the various languages used to study valued fields. They are intended as giving the necessary background to read the papers by Cluckers, Delon, Halupczok, Kowalski, Loeser and Macintyre in this volume. We also mention a few recent results or direction...

Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national s...

Working Papers Many of the documents in this series are prepublication/preprint articles, which may subsequently appear (part or whole) in peer reviewed journals and books. In most cases they are draft documents, the purpose of which is to foster discussion and debate, prior to publication elsewhere, whilst ideas are still fresh. Citation notice Citation should conform to normal academic standa...

Although the enthusiasm for the concept of globalisation has taken a darker complexion since 9/11, it still provides a convenient label for a variety of purposes. However, its attractions also make it unhelpful and misleading, not least because while it suggests increasing global unity, it is generally used to draw attention to the often competitive interactions between diverse societies and cu...

where α ∈ (, ], f : [, ]×R→R (R := (–∞, +∞)) is continuous. In view of a fractional differential equation’s modeling capabilities in engineering, science, economy and other fields, the last few decades have resulted in a rapid development of the theory of fractional differential equation; see the books [–]. This may explain the reason why the last few decades have witnessed an overgrowing...

These notes give a more detailed account of the material discussed in lectures. They are largely based on material found in books and research papers. In the former category, we have relied heavily on the following two texts:

The conference papers, along with the discussants' remarks and an introductory essay by Robert Haveman, have now appeared in A Decade of Federal Antipoverty Programs: Achievements, Failures, add Lessons-a volume edited by Haveman, Director of the lnstitute at the time of the Wingspread conference. This is the second volume in the Institute's Poverty Policy Analysis Series of books written for r...
