Foreword [spacer]

The formal system λδ (\lambda\delta) is a typed λ-calculus aiming to support the foundations of Mathematics that require an underlying specification language (for example the Minimal Type Theory and its predecessors).
-
+
λδ is developed in the context of the Hypertextual Electronic Library of Mathematics as a machine-checked digital specification - that is not the formal counterpart of some previously published informal material. -
-
- λδ comes in several versions listed in the following table, - which includes the major milestones: + that is not the formal counterpart of previous informal material.
