Chiral Symmetry {\it Breaking} in the Light-Cone Representation ($M_π^2 \sim μ_q <Ω|\barψψ|Ω> +...$)

In this paper I shall discuss the way in which vacuum structure and condensates occur in the light-cone representation. I shall particularly emphasize the mechanism by which the mass squared of a composite such as the pion comes to depend linearly on the bare mass of its Fermion constituents. I shall give details in two dimensions then discuss the case of four dimensions more speculatively.
