There are many different classifications of entanglement for multipartite quantum systems, one of which is based on the number of the unentangled particles. In this paper, we mainly study the quantum states containing at most k – 1 unentangled particles and provide several entanglement criteria based on the different forms of inequalities, which can both identify quantum states containing at most k – 1 unentangled particles. We show that these criteria are more effective for some states by concrete examples.
