... subset A of a group G is called symmetric with respect to the element g ∈ G if A = gA −1 g. It is proved that in any 2-coloring, every infinite group G contains monochrome symmetric subsets of arbitrarily ... the form g + U where U = −U. Such subsets were called symmetric and groups that can be partitioned into two subsets not containing infinite symmetric subsets – assymetrically resol...
