On Parametric Polymorphism and Irrelevance in MartinLöf Type Theory

Andreas Abel (2010)
Rejected from Logics in Computer Science, LICS 2010.
MLTT with ``Currystyle'' definitional equality. While a proof of consistency is given,
decidability of equality is unclear.
Still, the substitution calculus is interesting and
seems to work for irrelevance.
