+ 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 <a href="http://www.math.unipd.it/~maietti/">Minimal Type Theory</a>
+ and its predecessors).
+ </div>
+ <div xmlns:ld="http://lambdadelta.info/" class="text">
+ λδ is developed in the context of the
+ <a href="http://helm.cs.unibo.it/">Hypertextual Electronic Library of Mathematics</a>
+ as a machine-checked digital specification
+ that is not the formal counterpart of previous informal material.
