Ideals of the semigroup of ultrafilters of a topological group

We construct two new series of closed left ideals of the semigroup \(\bar \tau \) of ultrafilters of a topological group (G, τ). The first series gives a disjunctive decomposition of τ-absorbing ultrafilters. Under certain restrictions on the topology of the group (G, τ), the second series gives...
