Four lectureships in Nottingham

----------------------------------------------------------------------

		     THE UNIVERSITY OF NOTTINGHAM

	School of Computer Science and Information Technology

			  Four lectureships

Applications are  invited for the  above posts in a  rapidly expanding
School   based   at   one   of   the   UK's   strongest   research-led
universities. The School was graded  4 in the 1996 Research Assessment
Exercise and is  now building up its research  strengths for a further
improvement in  grade.  These posts are  part of a  steady increase in
the  size of the  School accompanied  by a  move to  new purpose-built
accommodation  in September 1999.  Although the  successful candidates
will have the opportunity of  teaching within their specialist area at
undergraduate and postgraduate level, there will also be a requirement
to teach  general computer science and  information technology modules
outside of any particular specialisation.

Candidates should already  have a PhD in computer  science, or another
closely related discipline, together  with strong evidence of existing
research  work  and the  potential  for  future  research at  Grade  5
level.  Outstanding  candidates will  be  welcomed  from  any area  of
computer science.

Salary will  be within  the range #17,238  - #30,065 per  annum (under
review), depending on qualifications and experience.

Informal enquiries  may be addressed to  Professor P H  Ford, tel: +44

PhD grant at INRIA Sophia Antipolis

See the second part of this message for a translation in English.

  Bourse de doctorat à l'INRIA Sophia Antipolis
                Projet Lemme

le projet Lemme de l'INRIA Sophia Antipolis propose une bourse de
doctorat centrée sur les méthodes formelles basées sur Coq et sur la
description de langages de programmation adaptés aux cartes à puces.
Cette thèse s'intègrera dans le cadre d'une collaboration avec GemPlus,
entreprise à la pointe du développement des cartes à puces, Les
techniques étudiées devront permettre de développer des vérificateurs
de byte-code formellement certifiés pour des langages approximant le
langage JavaCard.  L'objectif à terme est de fournir un vérificateur
de byte-code entièrement prouvé correct pour le langage JavaCard tel
qu'il est défini par JavaSun.

L'étudiant travaillant avec cette bourse doctorale aura l'occasion
d'approfondir ses compétences dans un domaine à l'intersection des
domaines théoriques les plus ambitieux de la logique et de
l'informatique fondamentale et des champs d'applications les plus
dynamiques de l'évolution récente des technologies de l'information et 
de la communication (authentification, sécurité sur les réseaux,
commerce électronique...).

Les candidats intéressés devront envoyer un curriculum vitae et une
lettre de motivation à Yves Bertot (Yves.Bertot <at> sophia.inria.fr).

symmetric frame of a suplattice: question


The symmetric frame of a sup-lattice L is the frame freely generated by L
with sups being preserved in the presentation. Classically (ie, with the
truth value object being 2) it is easy to show that the injection of
generators is 1-1. Does anyone know whether this also holds in an
arbitrary topos?

Thanks,

lifting and non-Artin gluing

                     Non-Artin Gluing in Recursion Theory
                   and Lifting in the Abstract Stone Duality

                       for "Category Theory 2000", Como

                  http://hypatia.dcs.qmw.ac.uk/author/TaylorP

    The analogy between `open' and `recursively enumerable' sets has long
    been a mainstay of theoretical computer science, but the traditional
    axiomatisation of general topology involving arbitrary unions is an
    obstacle to the formal unification of these disciplines.

    In particular, whilst Artin showed how to glue an open subspace
    to its closed complement using a comma square of frames, we give
    a diagonalisation argument to show that this representation fails for
    any recursively enumerable subset of $\mathbb N$ that is not decidable.

    Abstract Stone Duality is a re-axiomatisation based on the monadic
    adjunction between the dual categories of `frames' and `spaces'. Despite
    the failure of Artin gluing, we show in this formulation that the lift
    or scone, constructed using a comma square, still provides the classifier
    for partial maps with open domain of definition.  As the axiomatisation
    is not given in terms of finite intersections and arbitrary unions,
    a careful study of the modular law is needed to prove this.

I would very much like to receive comments and references to relevant work on
 *  Artin gluing and the partial map classifier FOR LOCALES (not toposes),
 *  modular lattices and the (Goursat?) equation  ab=bab  for idempotents.

I will be preparing an abridged version for the Como proceedings during the
