new dissertation and talk


Dear all,

I have just completed and successfully defended my dissertation
``Linear Set Theory,'' which is to be submitted to the department of
philosophy at Stanford University. I would like to post the abstract
of the thesis in this newsgroup. This is a LaTeX fle.

This dissertation work was supervised by Grigori Mints and 
Solomon Feferman. The result on LZF will be presented in 
the coming 1993-1994 ASL annual meeting in Gainesville, Florida, 
as one of the contributed papers (Sunday afternoon).  

Please note that my talk is NOT in the recently posted program of the
meeting since it was scheduled after the program had been in print.

Thank you very much,

Masaru Shirahata

Evolving Algebra semantics for LL (request)


Have anybody heard of (an attempt to develop) a semantics for LL in terms
of Evolving Algebras? Or maybe you think this would be a stupid idea?

Any information or suggestions will be appreciated. Please reply to
vladimir@... because I don't read the list.

TLCA: First Call for Papers (Plain Text and Latex)


First Call for Papers, TLCA
International Conference on Typed Lambda Calculi and Applications

April 10--12, 1995, Edinburgh, Scotland

The second international conference on Typed Lambda Calculi and 
Applications will be held April 10--12, 1995, at Edinburgh in Scotland.  
The conference aims at providing a forum for the presentation and 
discussion of recent research in the following areas:

Proof theory of type systems 
Logic and type systems 
Typed lambda calculi as models of (higher order) computation 
Semantics of type systems 
Proof verification via type systems 
Type systems of programming languages
Typed term rewriting systems

The program of TLCA will consist of about 30 selected presentations in 
plenary sessions.  The program committee for TLCA is chaired by 
M. Dezani and has the following members: 

 H. Barendregt  (Catholic University of Nijmegen)  
 M. Dezani  (Chairperson, University of Turin)  
 J-Y. Girard  (University of Marseilles)  
 R. Hindley  (University of Swansea)  
 F. Honsell  (University of Udine)  
 J. W. Klop  (CWI)  
 G. Longo  (ENS)

summer school on partial evaluation


                         PRELIMINARY ANNOUNCEMENT
                    SUMMER SCHOOL ON PARTIAL EVALUATION

                        A one-week intensive course

                        Carnegie Mellon University
                       Pittsburgh, Pennsylvania, USA
                     Tuesday-Saturday, July 5-9, 1994

         Charles Consel        Olivier Danvy           Peter Lee

Partial evaluation is an automatic program transformation technique that
specializes programs with respect to partial knowledge of their input.
Although simple in concept, partial evaluation has some rather surprising
applications and far-reaching implications for automatic program
transformation.  In particular, many problems can be shown to be
``specializations'' of a more general problem.  Partial evaluation has been
used in many areas such as compiler generation, scientific computing,
computer graphics, and pattern matching.

This summer school, to be held at Carnegie Mellon University in Pittsburgh,
Pennsylvania, aims at introducing the principles, techniques, and
applications of partial evaluation.  This presentation will be done in the
context of Consel's partial evaluator for procedural programs, called
Schism.  Students will get hands-on experience with the course concepts by
working directly with Schism, studying both its use and its internals.
Also, various applications of partial evaluation will be covered such as
pattern matching and parameterized programming.

Re: Evolving Algebra semantics for LL (request)

I think it's not quite the same, because in Kripke semantics one has
relatively fixed binary or ternary reachability relations, and the game
becomes actually interesting when you impose certain conditions on them
(reflexivity, transitivity, etc).

> Is there some intuition that makes evolving algebras

My intuition was very simple, not to call it naive: evloving algebras don't
have any problem with change (dynamics), and dynamics seems to be LL's most
salent feature. I'm not sure though I like the way dynamics is admitted
into EAs: it's the same way Einstein resolved the paradoxes with the speed
of light.

John, could you please set up public permissions to the last two summary
files (20.summary, 21.partial) on theory.stanford.edu: pub/linear?

I think this would just give you a form of possible-worlds (Kripke)
model. This would be nice if it worked, but I don't see how calling
such a thing an "Evolving Algebra" model would make it easier to 
construct one. Is there some intuition that makes evolving algebras
seem natural?

Papers available by Public ftp


Dear readers,

Firstly, apologies to those of you who get both the relevant logic
mailing list and the linear logic mailing list --- you'll get two
copies of this note.

Secondly, to all interested in work in substructural logics, I bring
to your attention a collection of my preprints in the area.  These
are available by public ftp from 

	arp.anu.edu.au

in the directory

	pub/papers/restall

The directory contains a file README with short descriptions of the 
works in the directory.  They include papers on substructural logics,
the philosophy of logic, and other areas of interest to relevant/linear
logicians.  I invite you to ftp over to take a look.  (The files can
be quite large.  They are compressed postscript files, and these can
be big.  If you have any problems downloading them, email me, and I
will see to getting a hardcopy to you.)

I would very much appreciate your comments if you download/read anything.

	Date: Mon, 28 Mar 1994 15:04:37 +1000
	From: Greg Restall <Greg.A.Restall@...>

	The directory contains a file README with short descriptions of the 
	works in the directory.  They include papers on substructural logics,

With regard to your "A Useful Substructural Logic" in that directory,
it is worth mentioning that this logic supports an equational
definition of transitive closure.  See my paper

	 <at> InProceedings(
Pr90b,	Author="Pratt, V.R.",
	Title="Action Logic and Pure Induction",
	Booktitle="Logics in AI: European Workshop JELIA '90, LNCS 478",
	Editor="J. van Eijck", Publisher="Springer-Verlag", Pages="97-120",
	Address="Amsterdam, NL", Month=Sep, Year=1990)

making this point, abstract appended, paper available by anonymous ftp
as boole.stanford.edu:/pub/jelia.tex.

At a talk at a 1992 conference:

Pr92c,  Author="Pratt, V.R.",
