Hi, whatWhat is the main use of Indiscerniblesindiscernibles in model theory? reading through Chang and Keisler's Model Theory it seems that the main motivation for Indicerniblesindicernibles is for getting many non isomorphic-isomorphic models for a theory (like the theory of dense linear order without endpoint). Also, can you recommend the best source for reading about Indiscerniblesindiscernibles and their uses?
Thanks.
