86 The formal system λδ (\lambda\delta) is a typed λ-calculus aiming to support
87 the foundations of Mathematics that require an underlying specification language
88 (for example the <a href="http://www.math.unipd.it/~maietti/">Minimal Type Theory</a>
89 and its predecessors).
91 <div xmlns:ld="http://lambdadelta.info/" class="text">
92 λδ is developed in the context of the
93 <a href="http://helm.cs.unibo.it/">Hypertextual Electronic Library of Mathematics</a>
94 as a machine-checked digital specification
95 that is not the formal counterpart of some previously published informal material.
