+  <span class="paper_abstract">
+      Most of the state-of-the-art proof assistants are based on procedural
+      proof languages, scripts, and rely on LCF tacticals as the primary tool
+      for tactics composition. In this paper we discuss how these ingredients
+      do not interact well with user interfaces based on the same interaction
+      paradigm of Proof General (the de facto standard in this field),
+      identifying in the coarse-grainedness of tactical evaluation the key
+      problem.
+
+      We propose tinycals as an alternative to a subset of LCF tacticals,
+      showing that the user does not experience the same problem if tacticals
+      are evaluated in a more fine-grained manner. We present the formal
+      operational semantics of tinycals as well as their implementation in the
+      Matita proof assistant.

+      Mathematical notation is a structured, open, and ambiguous language.  In
+      order to support mathematical notation in MKM applications one must
+      necessarily take into account presentational as well as semantic aspects.
+      The former are required to create a familiar, comfortable, and usable
+      interface to interact with.  The latter are necessary in order to process
+      the information meaningfully.  In this paper we investigate a framework
+      for dealing with mathematical notation in a meaningful, extensible way,
+      and we show an effective instantiation of its architecture to the field
+      of interactive theorem proving. The framework builds upon well-known
+      concepts and widely-used technologies and it can be easily adopted by
+      other MKM applications.

+  <span class="paper_abstract">
+      Mathematical notation has the characteristic of being ambiguous:
+      operators can be overloaded and information that can be deduced is often
+      omitted.  Mathematicians are used to this ambiguity and can easily
+      disambiguate a formula making use of the context and of their ability to
+      find the right interpretation.
+
+      Software applications that have to deal with formulae usually avoid these
+      issues by fixing an unambiguous input notation. This solution is annoying
+      for mathematicians because of the resulting tricky syntaxes and becomes a
+      show stopper to the simultaneous adoption of tools characterized by
+      different input languages.
+
+      In this paper we present an efficient algorithm suitable for ambiguous
+      parsing of mathematical formulae. The only requirement of the algorithm
+      is the existence of a validity predicate over abstract syntax trees of
+      incomplete formulae with placeholders. This requirement can be easily
+      fulfilled in the applicative area of interactive proof assistants, and in
+      several other areas of Mathematical Knowledge Management.
