The Eighth International Conference on Computability, Complexity and Randomness (CCR 2013) will be held in Moscow, at the Poncelet lab, from the 23rd to the 27th of September 2013. http://ccr2013.mccme.ru/ The conference, previously also known as the conference on Logic, Computability and Randomness, will be in the tradition of the previous meetings Cordoba, Buenos Aires, Nanjing, Luminy, Notre Dame, Cape Town, and Cambridge. Topics covered include: * Algorithmic randomness, * Computability theory, * Kolmogorov complexity, * Computational complexity, * Reverse mathematics and logic. Authors are invited to submit an abstract in PDF format of typically about 1 or 2 pages via the following web page: http://www.easychair.org/conferences/?conf=ccr2013 No full papers will be required for this conference. The deadline for submissions is 15th May 2013. After the deadline for submissions has expired, submissions may still be accepted for reviewing at the discretion of the PC chair. Note though that the visa application process may be lengthy, so submissions are encouraged well before the official deadline. Funding opportunities for student members of the Association for Symbolic Logic are available. Applications should be directed to the Association for Symbolic Logic three months prior to the meeting, following the instructions at: http://www.aslonline.org/studenttravelawards.html Invited speakers: * George Barmpalias * Laurent Bienvenu * Edward Hirsch * Emmanuel Jeandel * Jan Reimann * Alexander Shen * Michael Yampolsky * Yang Yue * Sergey Yekhanin The programme committee consists of Eric Allender (Rutgers, USA), Mark Braverman (Princeton, USA), Vasco Brattka (Munich, Germany), Willem Fouche (Pretoria, South Africa), Noam Greenberg, chair (Wellington, New Zealand), Mathieu Hoyrup (Nancy, France), Andre Nies (Auckland, New Zealand), Theodore Slaman (Berkeley, USA), and Frank Stephan (Singapore).
