title: General pseudoadditivity of composable entropy prescribed by the existence of equilibrium.
abstract: The concept of composability states that entropy of the total system composed of independent subsystems is a function of entropies of the subsystems. Here, the most general pseudoadditivity rule for composable entropy is derived based only on the existence of equilibrium.
