We investigate the model-theoretic invariant κ s r d m (T), which was introduced by Shelah, and prove that κ s r d m (T) is sub-additive. An infinite value of κ s r d m (T) leads to the equality κ s r d m (T)= κ s r d 1 (T). We apply the same proof method to analyze the other invariant κ i r d m (T) and show that it is also sub-additive, achieving an improvement of Shelah's result.
