We consider the metric space of all toric K¨ahler metrics on a compact toric manifold; when “looking at it from infinity” (following
Gromov), we obtain the tangent cone at infinity, which is parametrized by equivalence classes of complete geodesics. In
the present paper, we study the associated limit for the family of metrics on the toric variety, its quantization, and degeneration of
generic divisors.
The limits of the corresponding K¨ahler polarizations become degenerate along the Lagrangian fibration defined by the moment
map. This allows us to interpolate continuously between geometric quantizations in the holomorphic and real polarizations and
show that the monomial holomorphic sections of the prequantum bundle converge to Dirac delta distributions supported on BohrSommerfeld fibers.
In the second part, we use these families of toric metric degenerations to study the limit of compact hypersurface amoebas and
show that in Legendre transformed variables they are described by tropical amoebas. We believe that our approach gives a different,
complementary, perspective on the relation between complex algebraic geometry and tropical geometry.
