This paper is a systematic approach to the construction of coronas (i.e. Higson dominated boundaries at infinity) combable spaces. We introduce three additional properties for combings: properness, coherence and expandingness. Properness condition under which our corona works. Under assumption expandingness, attaching Rips complex yields contractible [Formula: see text]-compact space in sits as...
