Topics: constructive mathematics, constructive analysis, computable 
analysis, exact real number computation

CCC is a workshop series that brings together researchers applying 
logical methods to the development of algorithms, with a particular 
focus on computation with infinite data, where issues of continuity, 
computability and constructivity play major roles. Specific topics 
include exact real number computation, computable analysis, effective 
descriptive set theory, constructive analysis and topology, and related 
areas. The overall aim is to apply logical methods in these disciplines 
to provide a sound foundation for obtaining exact and provably correct 
algorithms for computations with real numbers and other continuous data, 
which are of increasing importance in safety-critical applications and 
scientific computation.
