It is an interesting and important question to determine the character formula of irreducible representations of semisimple Lie algebras (or algebraic groups). Since Kazhdan-Lusztig polynomials appeared in 1979, this field has obtained numerous remarkable results.We will mainly introduce the method to construct KL polynomials. Before this, some basics in semisimple LIe algebras are reviewed.
