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.


Previous workshops have been held in Cologne 2009, Trier 2012, Gregynog
2013, Ljubljana 2014, Kochel 2015, Nancy 2017, Faro 2018, Ljubljana
