摘要：We begin by revisiting partiality in univalent type theory via the notion of dominance. We then perform first steps in constructive computability theory, discussing the consequences of working with computability as property or structure, without assuming countable choice or Markov's principle. A guiding question is what, if any, notion of partial function allows the proposition "all partial functions on natural numbers are Turing computable" to be consistent.
