  We show that (a) the conformal properties of Anti-de Sitter (AdS) space, (b)
the properties of a field theory in one dimension under the full conformal
group found by de Alfaro, Fubini and Furlan, and (c) the frame-independent
single-variable light-front Schr\"odinger equation for bound states all lead to
the same result: a relativistic nonperturbative model which successfully
incorporates salient features of hadronic physics, including confinement,
linear Regge trajectories, and results which are conventionally attributed to
spontaneous chiral symmetry breaking.
