Economical unification of three families in SO(18).
We present the explicit construction of an SO(18) model that yields only three fermion families, along with their mirror partners, about or below the weak scale. The complete Higgs-field content that… Expand
Erratum: Symmetry-breaking patterns in QCD with 27 scalars
Symmetry-breaking patterns in QCD with 27 scalars.
We investigate the symmetry-breaking patterns of the SU(3)-invariant Higgs potential with the 27 scalar fields. We find that the absolute minima can be invariant under subgroups yielding one, two,… Expand
Symmetry breaking of SU(n) gauge theories to maximal regular subgroups and fourth-rank tensors.
We study the problem of spontaneous symmetry breaking of SU(n) gauge theories. We consider the breaking with fourth-rank tensors to maximal regular subgroups of SU(n). We derive explicit solutions of… Expand
Possible phase transitions among Calabi-Yau compactifications.
We study a wide class of complex spaces each of which may be spanned by ''internal'' degrees of freedom of certain physics models with simple supergravity in (3+1)-dimensional Minkowski space-time.… Expand
Grand unification of three light generations.
We propose an SO(18) grand unified model that predicts three light generations, if the horizontal symmetry below the grand-unification scale is chosen to be Sp(4) x SU(2)/sub d/. A novel feature of… Expand

The idea that the universe passed through a short inflationary epoch  at very early times (≪ 10-5 sec) involving an exponential expansion of the scale factor is most attractive because it resolves… Expand
Invariants of self-adjoint rank-four SU(n) tensors.
We study the problem of the choice of a linearly independent set of quadratic, cubic, and quartic invariants which is needed for the construction of Higgs potentials. Concentrating on self-adjoint… Expand
Nonminimal SU(5) model.
The existence of the solution of the symmetry-breaking problem SU(5)..-->..SU(3) x SU(2) x U(1)/sub Y/..-->..SU(3) x U(1)/sub Q/ is shown in a nonminimal model where the 75-dimensional Higgs field is… Expand
Finite distance between distinct Calabi-Yau manifolds.
Moduli spaces for a wide class of Calabi-Yau manifolds with different numerical invariants (and thus topologically distinct) can be assembled into a connected ''web'' in which all distances are… Expand
