Kähler manifolds are a special type of complex manifold with a Kähler metric that aligns with the complex structure. They are essential in differential geometry and complex analysis, with applications in theoretical physics and algebraic geometry. Examples include complex projective spaces and various classifications like Fano, Calabi-Yau, and Hyperkähler manifolds. Advanced research delves into Kähler-Ricci flow and holomorphic vector fields.
