31. In type theory , the logical view is exchanged for a more computational view of objects. 32. In 2009 he constructed the univalent model of Martin-L�f type theory in simplicial sets. 33. It is also similar to the unit type used in functional programming languages and type theory . 34. It connected the " computational component " of many type theories to the derivations in logics. 35. The lambda cube was not a new type theory but a categorization of existing type theories. 36. The lambda cube was not a new type theory but a categorization of existing type theories . 37. The formal design and study of type systems is known as " type theory ". 38. :I apologize but my computer science studies were cut short before I got to type theory . 39. See Curry & ndash; Howard isomorphism for the general context of what this implies in type theory . 40. Type theory internalizes the interpretation of intuitionistic logic proposed by Kolmogorov, the so-called BHK interpretation.
