摘要:As a generalization of the classical killing-contractible-complex lemma, we present algebraic Morse theory  via homological perturbation theory, in a form more general than existing presentations in the literature. We also give a criterion for the two-sided Anick resolution to be a minimal resolution. At last, we apply algebraic Morse theory to Chinese algebras and show that a Chinese algebras of rank $n$ is homologically smooth and of global dimension $\frac{n(n+1)}{2}$.
