Fourth International Conference on Computability and Complexity in
Analysis CCA'2007
June 16-18, 2007
Siena, Italy

Scope

The conference is concerned with the theory of computability and
complexity over real-valued data.

Computability and complexity theory are two central areas of
research in mathematical logic and theoretical computer science.
Computability theory is the study of the limitations and abilities
of computers in principle. Computational complexity theory provides
a framework for understanding the cost of solving computational
problems, as measured by the requirement for resources such as time
and space. The classical approach in these areas is to consider
algorithms as operating on finite strings of symbols from a finite
alphabet. Such strings may represent various discrete objects such
as integers or algebraic expressions, but cannot represent general
real or complex numbers, unless they are rounded.

Most mathematical models in physics and engineering, however, are
based on the real number concept. Thus, a computability theory and a
complexity theory over the real numbers and over more general
continuous data structures is needed. Unlike the well established
classical theory over discrete structures, the theory of computation
over continuous data is still in early stages of development,
despite remarkable progress in recent years. Many important
fundamental problems have not yet been studied, and presumably
numerous unexpected and surprising results are waiting to be
detected.

Scientists working in the area of computation on real-valued data
come from different fields, such as theoretical computer science,
domain theory, logic, constructive mathematics, computer arithmetic,
numerical mathematics and all branches of analysis. The conference
provides a unique opportunity for people from such diverse areas to
meet, present work in progress and exchange ideas and knowledge.

The topics of interest include foundational work on various models
and approaches for describing computability and complexity over the
real numbers. They also include complexity-theoretic investigations,
both foundational and with respect to concrete problems, and new
implementations of exact real arithmetic, as well as further
developments of already existing software packages. We hope to gain
new insights into computability-theoretic aspects of various
computational questions from physics and from other fields involving
computations over the real numbers.

This year CCA 2007 is co-located with the conference CiE 2007,
Computability in Europe 2007: Computation and Logic in the Real
World, University of Siena, June 18-23, 2007.
