21. Quadrantid Meteors
The annual Quandrantid meteor shower makes its return in 2007 from 1st - 6th January. ... Viewing conditions, however, for the shower this time around are somewhat unfavourable as the peak of activity occurs near full Moon thus making it difficult to observe the fainter meteors. ... Peter Jenniskens of the NASA Ames Research Center in California, USA has pointed out that the source for the Quadrantids might be a recently discovered asteroid, or inert comet, 2003 EH1. ...

35. Rings of continuous functions (Fall 2008)
... Цель спецкурса - изложение теории кольца C(X) всех непрерывных функций на вполне регулярном топологическом пространстве X (например, для X=R, N или Q), а также его подкольца Cb(X), состоящего из всех непрерывных ограниченных функций. Будут рассмотрены максимальные и простые идеалы, z-идеалы и их кольца вычетов. Например, кольца вычетов по максимальным идеалам C(X) могут быть неархимедовыми полями, содержащими R - так называемыми гипердействительными полями. ... Упорядоченные кольца вычетов. ...
