Title
Syndetic Submeasures And Partitions Of G-Spaces And Groups
Abstract
We prove that for every k is an element of N, each countable infinite group G admits a partition G = A boolean OR B into two sets which are k-meager in the sense that for every k-element subset K subset of G the sets K A and K B are not thick. The proof is based on the fact that G possesses a syndetic submeasure, i.e. a left-invariant submeasure mu : P(G) -> [0, 1] such that for each epsilon > 1/vertical bar G vertical bar and subset A subset of G with mu(A) < 1 there is a set B subset of G\A such that mu(B) < epsilon and F B = G for some finite subset F subset of G.
