 # Kripke-style untyped NbE in racket
 [![status-badge](https://woodpecker.electriclam.com/api/badges/4/status.svg)](https://woodpecker.electriclam.com/repos/4)

 An implementation of normalization by evaluation loosely based on [A
 Denotational Account of Untyped Normalization by
 Evaluation](https://www.brics.dk/RS/03/40/BRICS-RS-03-40.pdf) and
 [Abel's thesis on NbE](https://www.cse.chalmers.se/~abela/habil.pdf).
 
 Since the implementation is untyped, the `normalize` function only
-gives you β-normal forms. However, you can get a little bit of
-βη-equivalence by invoking Coquand's algorithm (`η-eq?`) on
-β-normal forms.
+gives you $\beta$-normal forms. However, you can get a little bit of

 I'm hoping to expand the repository into a benchmark suite where I can
 visualize the performance trade-off of type-directed NbE compared to
