The purpose of this article is to prove the following higher dimensional Miyaoka-Yau inequality (for open algebraic manifolds defined over \({\mathbb{C}}).\) Theorem. Let X be a projective algebraic manifold defined over \({\mathbb{C}}\) and let D be a divisor with only normal crossings on X. Assume that for every sufficiently small positive rational number \(\epsilon\), \(K_ X+(1- \epsilon)D\) is ample. Then the inequality \(c^ n_ 1(\Omega_ X(\log (D)))\leq 2(2n+1)\cdot c_ 1^{n-2}(\Omega_ X(\log (D)))\cdot c_ 2(\Omega_ X(\log (D)))/n,\quad n=\dim X\) holds.
