WoLLIC is an annual international forum on inter-disciplinary research involving formal logic, computing and programming theory, and natural language and reasoning. Each meeting includes invited talks and tutorials as well as contributed papers. The twentieth WoLLIC will be held at the Technische Universität Darmstadt, Germany, from August 20th to 23rd, 2013. It is sponsored by the Association for Symbolic Logic (ASL), the Interest Group in Pure and Applied Logics (IGPL), the The Association for Logic, Language and Information (FoLLI), the European Association for Theoretical Computer Science (EATCS), the European Association for Computer Science Logic (EACSL), the Sociedade Brasileira de Computação (SBC), and the Sociedade Brasileira de Lógica (SBL).


Paper submission
Contributions are invited on all pertinent subjects, with particular interest in cross-disciplinary topics. Typical but not exclusive areas of interest are: foundations of computing and programming; novel computation models and paradigms; broad notions of proof and belief; formal methods in software and hardware development; logical approach to natural language and reasoning; logics of programs, actions and resources; foundational aspects of information organization, search, flow, sharing, and protection. Proposed contributions should be in English, and consist of a scholarly exposition accessible to the non-specialist, including motivation, background, and comparison with related works. They must not exceed 10 pages (in font 10 or higher), with up to 5 additional pages for references and technical appendices. The paper's main results must not be published or submitted for publication in refereed venues, including journals and other scientific meetings. It is expected that each accepted paper be presented at the meeting by one of its authors. Papers must be submitted electronically at the WoLLIC 2012 EasyChair website. (Please go to http://wollic.org/wollic2013/instructions.html for instructions.) A title and single-paragraph abstract should be submitted by March 25th, and the full paper by March 29th (firm date). Notifications are expected by May 3rd, and final papers for the proceedings will be due by May 15th (firm date).

Proceedings
The proceedings of WoLLIC 2013, including both invited and contributed papers, will be published in advance of the meeting as a volume in Springer's LNCS series. In addition, abstracts will be published in the Conference Report section of the Logic Journal of the IGPL, and selected contributions will be published as a special post-conference WoLLIC 2013 issue of a scientific journal (to be confirmed).
