Хроматические числа и проблема Борсука А.М. Райгородский 1 Хроматические числа Назовем хроматическим числом евклидова пространства R n минимальное количество цветов, в ко- торые можно так покрасить все точки R n , чтобы между одноцветными точками не было расстояния 1. ... Упражнение 1. ... Задача отыскания хроматического числа тесно связана с теорией графов. ... 3 Подобно тому, как при изучении хроматических чисел были полезны графы расстояний, при работе с числом Борсука нужны графы диаметров. ...

The probability density function (PDF) is a simple analytical tool for determining the hierarchical spatial structure of molecular clouds. ... We have recently conducted a PDF analysis of the molecular gas in the G333 and Vela C giant molecular cloud complexes, using transitions of CO, HCN, HNC, HCO+ and N2H+. The results show that CO and its isotopologues trace mostly the log-normal part of the PDF, while HCN and HCO+ trace both a log-normal part and a power law part to the distribution. ...
