Wentsün, Wu, On Chern Numbers of Algebraic Varieties with Arbitrary Singularities, Acta Mathematica Sinica, New Series Chinese Journal of Mathematics, 3(3), 1987, pp. 227-236
In 1965 the author introduced the notion of Chern classes for an algebraic variety with arbitrary singularities. Based on this definition the well-known Miyaoka-Yao inequalities have been proved and extended by quite simple direct computations.
