Phrase: Calabi conjecture on Kähler metrics with prescribed Ricci curvature | Statement: [Eugenio Calabi, theoryDeveloped, Calabi conjecture on Kähler metrics with prescribed Ricci curvature]

Target entity: Calabi conjecture on Kähler metrics with prescribed Ricci curvature
Context triple: [Eugenio Calabi, theoryDeveloped, Calabi conjecture on Kähler metrics with prescribed Ricci curvature]

• A. Calabi conjecture chosen
  The Calabi conjecture is a fundamental result in complex differential geometry, proved by Shing-Tung Yau, which characterizes when a compact Kähler manifold admits a unique Ricci-flat Kähler metric in a given Kähler class.
• B. Kähler–Ricci flow
  Kähler–Ricci flow is a geometric evolution equation that deforms Kähler metrics on complex manifolds according to their Ricci curvature, playing a central role in complex differential geometry and the study of canonical metrics.
• C. Calabi–Bernstein theorem
  The Calabi–Bernstein theorem is a result in differential geometry that characterizes entire maximal spacelike hypersurfaces in Minkowski space as necessarily being affine hyperplanes.
• D. Donaldson–Uhlenbeck–Yau theorem
  The Donaldson–Uhlenbeck–Yau theorem is a fundamental result in differential and algebraic geometry that characterizes when a holomorphic vector bundle over a compact Kähler manifold admits a Hermitian–Einstein metric, linking geometric stability with the existence of such metrics.
• E. Nirenberg problem in differential geometry
  The Nirenberg problem in differential geometry is a classical question about prescribing Gaussian curvature on the 2-sphere via conformal deformations of the metric.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
