LF (Pfenning 91, Harper-Honsell-Plotkin 93) is a certain logical framework based on dependent intuitionistic type theory. Variants include the Edinburgh logical framework, abbreviated “Elf”, and linear LF, abbreviated LLF (Pfenning 96), the latter capturing also dependent linear type theory.
The logical framework LF originates around
