Remembering Raoul Bott

Figure 1. Raoul Bott in 2002. Raoul Bott passed away on December 20, 2005. Over a five-decade career he made many profound and fundamental contributions to geometry and topology. This is the second part of a two-part article in the Notices to commemorate his life and work. The first part was an authorized biography, “The life and works of Raoul Bott” [4], which he read and approved a few years ...

The Life and Works of Raoul Bott

In a career spanning five decades, Raoul Bott has wrought profound changes on the landscape of geometry and topology. It is a daunting task to improve upon his own reminiscences [B3], [B4], [B1] and commentaries on papers [B5], punctuated as they are by insight, colorful turns of phrases and amusing anecdotes. This article, based on his writings and on interviews and correspondences with people...

We introduce a new class of noncommutative rings-Galois orders, realized as certain subrings of invariants in skew semigroup rings, and develop their structure theory. The class of Galois orders generalizes classical orders in noncommutative rings and contains many classical objects, such as the Generalized Weyl algebras, the universal enveloping algebra of the general linear Lie algebra, assoc...

CORAL reefs are complex ecosystems threatened globally with a variety of natural and anthropogenic factors. Scientific monitoring is the primary source of information on reef biology and status. However, monitoring is both a scientific endeavor and a decisionmaking management tool. As a result, this dual nature leads to controversy and there is considerable debate among scientists about the des...
