<Indira Chatterji> studies <geometric group theory>. Her joint work with <Graham Niblo> develops a route from actions on a <wallspace> to actions on a <CAT(0) cube complex>.<From wall spaces to CAT(0) cube complexes by Indira Chatterji and Graham Niblo>[Original byline and abstract]{ref}
The distinction between a distance and a <pseudometric> matters here: different points can be separated by no walls. Counting walls still records enough separation information to support a cubical construction and transfer proper-action properties under the paper's hypotheses.<From wall spaces to CAT(0) cube complexes by Indira Chatterji and Graham Niblo>[Section 1 and main construction]{ref}
