My PhD thesis Playing with Truth is a collection of papers that revolve around the topic of self-referential truth.Given a language which contains Liar sentences, Truthtellers and what have you: Which sentences are assertible? Which are deniable? Which inferences are correct? My thesis develops three interrelated frameworks to answer these questions. A common feature of the frameworks is that they allow us to formalize the notion of an assertoric norm; the mentioned questions are answered relative to the specification of such a norm.  The frameworks shed novel light on the notions of assertion, denial and truth, which is testified by the various philosophical applications of the frameworks  that are discussed in my thesis.
