<p><b>Special Event</b><br><span style="font-family:arial, sans-serif;font-size:13px"><span style="font-family:Arial, Helvetica, sans-serif;font-size:medium">(tba)</span></span></p><p><span style="font-family:arial, sans-serif;font-size:13px"><span style="font-family:Arial, Helvetica, sans-serif;font-size:medium"></span></span><b>Paper submission</b></p>
<p>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 The paper's main results must not be published or submitted for publication in refereed venues, including journals and other scientific meetings.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 2011 EasyChair website. (Please go to <a href="http://wollic.org/wollic2011/instructions.html" target="_blank"><font color="#000000">http://wollic.org/wollic2011/instructions.html</font></a> for instructions.) A title and single-paragraph abstract should be submitted by January 1st, and the full paper by January 8 (firm date). Notifications are expected by February 21, and final papers for the proceedings will be due by March 1 (firm date).</p>
</div><div><p><b>Proceedings</b><br>The proceedings of WoLLIC 2011, including both invited and contributed papers, will be published in advance of the meeting as a volume in Springer's <a href="http://www.springer.com/lncs" target="_blank"><font color="#000000">LNCS</font></a> series. In addition, abstracts will be published in the Conference Report section of the <em>Logic Journal of the IGPL</em>, and selected contributions will be published as a special post-conference WoLLIC 2011 issue of a scientific journal (soon to be announced).</p>
