| Abstract: | The study of inequalities of Chern classes of varieties (also known as the geographical problem of varieties) is an important topic in algebraic geometry. The important inequalities include the famous Miyaoka-Yau inequality and the Noether inequality. Mainly study the Chern classes of complete intersection varieties. We obtain the Chern classes of the complete intersection varieties by the exact sequences of cotangent bundles, and establish some inequalities of the Chern classes of four-dimensional complete intersection varieties. |
