RealComp'98: CFP and preliminary programme

[Among other subjects, the following tutorial workshop / summer school
will cover semantics of real number computation and extensions of PCF
with a real number data type.  Therefore, it might be of interest to
TYPES readers.]

                   REAL NUMBER COMPUTATION

                        (RealComp'98)

              Tutorial Workshop / Summer School

              
June 19-20, 1998 Indianapolis, Indiana, USA
preceding the IEEE Symposium on Logic in Computer Science (LICS)

*** EARLY REGISTRATION ENDS MAY 15 ***


Motivation

  The usual implementation of real numbers in today's computers as
floating point numbers has the well-known deficiency that most numbers
can only be represented up to some fixed accuracy. This means that
even the basic arithmetic operations can not be performed exactly,
leading to the ubiquitous round-off errors. This is a serious problem
in all disciplines where high accuracy calculations are required. Many
different disciplines deal with Real Number Computation in a broad
sense. One of the ultimate goals of the theoretical and practical
research in this area is to overcome the above mentioned problems by
improving the present implementations and algorithms or providing
alternatives.



Aims and Scope

  The meeting aims to present an introduction to the interdisciplinary
area of Real Number Computation. The subject is understood in a broad
sense and covers various different fields like Recursion Theory,
Interval Analysis, Computer Arithmetic, Semantics of Programming
Languages and Numerical Analysis.  All talks will be accessible to
graduate students in any area of computer science, logic and
mathematics.  The workshop is also meant to provide researchers from
the various different communities an opportunity to meet and exchange
ideas.

Time and Place

  The workshop will take place at the Indiana University Conference
Center in Indianapolis, Indiana (USA) on Friday and Saturday, 19-20
June, 1998, just before the Symposium on Logic in Computer Science
(LICS), which will be on 21-24 June. Local information is available
from the LICS'98 server at http://www.lics98.cs.indiana.edu.

  RealComp'98 is in parallel with a Workshop on Probabilistic Methods
in Verification (PROBMIV'98). Participants of either workshop will be
able to attend the other.



Registration

        The registration fee is $115 if payed until May 15 and $130
after that. It includes a registration package, lunches for the days
attended and food service 7:30 - 4:30 (including coffee breaks). To
