108 The formal system λδ (\lambda\delta) is a typed λ-calculus aiming to support
109 the foundations of Mathematics that require an underlying specification language
110 (for example the <a href="http://www.math.unipd.it/~maietti/">Minimal Type Theory</a>
111 and its predecessors).
113 <div xmlns:ld="http://lambdadelta.info/" class="text">
114 λδ is developed in the context of the
115 <a href="http://helm.cs.unibo.it/">Hypertextual Electronic Library of Mathematics</a>
116 as a machine-checked digital specification
117 that is not the formal counterpart of previous informal material.
