When does weak normalization imply strong normalization?
Is there a possibility to get strong normalization for some kind of $\lambda$-calculus out of weak normalization with some other assumptions?
For example:
The term $(\lambda_y z)((\lambda_x xx)(\...

Criterion for the consistency of pure type systems
Pure type systems are characterized in an almost combinatorial way: a set of axioms $\star_i : \star_j$, and a set of triples $(\star_i, \star_j, \star_k)$ saying when the dependent product $\prod_{x :...

Understanding Strong Normalization for Identity Types in Martin-Löf Intensional Type Theory [closed]
Roughly, the strong normalization property for Martin-Löf Intensional Type Theory (MITT) tells us that every closed term $t$ of type $M$ will eventually reach a canonical normal form $t’$ such that it ...
