The formal systems of the λδ (\lambda\delta) family are typed λ-calculi aiming to support
- the foundational frameworks for Mathematics that require an underlying specification language
- (for example the <link to="http://www.math.unipd.it/~maietti/">Minimalist Foundation</link>
- and its predecessors).
