Query: Scalar and vector gauges unification in de Sitter ambient space
  formalism   We consider the massless minimally coupled scalar field in the de Sitter
ambient space formalism as a gauge potential or connection field. We construct
the scalar gauge theory by helping an arbitrary constant five-vector field
$B^\alpha$ analogous to the standard gauge theory. The Lagrangian density of
the interaction between the scalar and spinor fields is presented in this
framework. The Yukawa potential can be extracted from this Lagrangian in the
null curvature limit by an appropriate choice of a constant five-vector field.
It is shown that the de Sitter ambient space formalism permits us to unify the
gauge scalar and vector fields. By choosing a matrix form for the constant
five-vector field $B^\alpha$, the unification of gauge scalar and vector fields
in the spectral action of noncommutative geometry can be rewritten. We discuss
that the scalar gauge field may be interpreted as the connection fields between
the different de Sitter hyperboloids in the fuzzy quantum geometry due to the
constant five-vector field.
