We propose a supersymmetric SU(5)xSU(5) model, where the quarks and leptons
live in a U(1) product group theory space that is compactified on the real
projective plane RP^2. The fermion generations are placed on different points
in the deconstructed manifold by assigning them SO(10) compatible U(1) charges.
The observed masses and mixing angles of quarks and leptons emerge from
non-renormalizable operators involving the chiral link fields. The link fields
introduce a large atmospheric neutrino mixing angle \theta_23 via a dynamical
realization of the seesaw mechanism, which sets the deconstruction scale to a
value of the order the B-L breaking scale 10^14 GeV. Supersymmetry breaking can
be achieved through topological effects due to a non-trivial homology group
Z_2. The mixed anomalies of the link fields are canceled by Wess-Zumino terms,
which are local polynomials in the gauge and link fields only. We also comment
on the construction of Chern-Simons couplings from these fields.Comment: 22 pages, 2 figures, typos in neutrino mass squared differences
