摘要翻译:
本文研究了紧致环面流形上所有环面k“Ahler度量的度量空间,当”从无穷远看它“(遵循Gromov)时,我们得到了由完全测地线的等价类参数化的无穷远切锥。本文研究了环面变化度量族的相关极限、量化和泛型因子的退化。相应的k”Ahler极化的极限沿矩映射定义的拉格朗日纤维退化。这使得我们可以在全纯和实偏振中的几何量子化之间连续插值,并证明了前量子束的单全纯截面收敛于玻尔-索末菲光纤上的狄拉克δ分布。在第二部分中,我们利用这些多曲度规退化族研究了紧致超曲面变形虫的极限,并证明了在Legendre变换变量中,它们是由热带变形虫描述的。我们相信我们的方法在复代数几何和热带几何之间的关系上给出了一个不同的、互补的视角。

英文摘要:
  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 Bohr-Sommerfeld 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.
