Abstract
Given a reflection group acting on a complex vector space , a reflection map is the composition of an embedding with the orbit map that maps a -orbit to a point. Reflection maps can be very singular, but we give tools to study them easily. We find obstructions to -stability of reflection maps and produce, in the unobstructed cases, infinite families of -finite map-germs of any corank. We also relate them to conjectures of L\^e, Mond and Ruas.
