Dynamical Zeta Functions and Transfer Operators, Volume 49, Number 8

C ertain generating functions—encoding properties of objects like prime numbers, periodic orbits, ...—have received the name of zeta functions. They are useful in studying the statistical properties of the objects in question. Zeta functions have generally been associated with problems of arithmetic or algebra and tend to have common features: meromorphy, Euler product formula, functional equat...

The World of Blind Mathematicians, Volume 49, Number 10

1246 NOTICES OF THE AMS VOLUME 49, NUMBER 10 A visitor to the Paris apartment of the blind geometer Bernard Morin finds much to see. On the wall in the hallway is a poster showing a computergenerated picture, created by Morin’s student François Apéry, of Boy’s surface, an immersion of the projective plane in three dimensions. The surface plays a role in Morin’s most famous work, his visualizati...

Claude Elwood Shannon (1916–2001), Volume 49, Number 1

While his incredibly inventive mind enriched many fields, Claude Shannon's enduring fame will surely rest on his 1948 work " A mathematical theory of communication " [7] and the ongoing revolution in information technology it engendered. Shannon, born April 30, 1916, in Petoskey, Michi-gan, obtained bachelor's degrees in both mathematics and electrical engineering at the University of Michigan ...
