• (approximate) essential amenability
• (approximate) n-weak amenability
• (approximate) cyclic amenability

For two Banach algebras A and B, an interesting product A x(theta) B, called the theta-Lau product, was recently introduced and studied for some nonzero characters theta on B. Here, we characterize some notions of amenability as approximate amenability, essential amenability, n-weak amenability and cyclic amenability between A and B and their theta-Lau product.
