Boolean Function Representation Based on Disjoint-Support Decompositions
The Multi-Level Decomposition Diagrams (MLDDs) of this paper are a canonical representation of Boolean functions expliciting disjoint-support decompositions. MLDDs allow the reduc...

Free Theorems and Runtime Type Representations
’s abstraction theorem [21], often referred to as the parametricity theorem, can be used to derive properties about functional programs solely from their types. Unfortunately, i...
