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 ...
متن کاملThe 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...
متن کاملAxonal Firing in a Lobster Mechanoreceptor Neurone by Denis Combes,
1. A primary mechanosensory neurone, the anterior gastric receptor (AGR) associated with gastric mill muscle in the lobster foregut was examined in vitro with extraand intra-cellular recording techniques to understand processes of dendritic integration and dendro-axonal communication. 2. AGR has a 'T'-shaped geometry; its two long (> 3 mm) primary dendrites project distally to spatially separat...
متن کاملMolecular lines studies at redshift greater than 1 Francoise Combes
Observations of CO molecules in the millimetrer domain at high redshift (larger than 1), have provided interesting informations about star formation efficiency, and its evolution with redshift. Due to the difficulty of the detections, selection effects are important. The detection if often due to gravitational amplification. Objects selected by their (far)infrared flux, are in general associate...
متن کاملQuadratic Form Techniques and the Balslev-Combes Theorem
We extend the theorem of Balslev and Combes on the absence of singular continuous spectrum to a class of interactions including r~ (3/2 ̂ α < 2) local potentials. In addition, we note that the theory of sectorial operators allows a simplification of their proof and allows one to push the cuts through angles larger than the π/2 restriction employed by Balslev-Combes.
