Abstract

In this paper, we prove that a compact K\"ahler manifold XX with pseudo-effective (resp. singular positively curved) tangent bundle admits a smooth (resp. locally constant) rationally connected fibration ϕ ⁣:XY\phi \colon X \to Y onto a finite \'etale quotient YY of a compact complex torus. This result extends the structure theorem previously established for smooth projective varieties to compact K\"ahler manifolds.
