Theor. 43 (2010) 434004. journal of Physics A: Mathematical and Theoretical Dear colleagues, This has been another successful year for Journal of Physics A: Mathematical and Theoretical. More people than ever before are reading the journal and enjoying issues of high-quality research throughout theoretical and mathematical physics. This collection of highlights displays some of the most highly rated articles published in the journal over the course of 2010. All of these were chosen primarily for their high-quality science. This selection also displays the broad scope of the journal and shows that it is a meeting place for researchers to share mathematically rich work across different disciplines. Some of our best articles have been published as fast track communications (FTCs). FTCs are short articles presenting important new developments in mathematical and theoretical physics. FTCs benefit from accelerated publication, are free-to-read Impact Factor and benefit from our recommended reader service, where we will notify researchers 1.641* of the author’s choice when the article is published. * As listed in ISI®’s 2010 Science Citation Index journal citation reports This collection also shows details of the topical reviews and special issues that we have published throughout 2010. aVERAGE DoWNLOADS Topical reviews are commissioned by our Board Members to provide timely pEr ARTIcLE overviews of the current state of research in areas of great interest and activity, while special issues are collections of articles focused on contemporary areas of research, with contributions from world-class authors, and guest edited by leading 139 researchers. 2011 will be another strong year for the journal, with special issues planned on Full-text downloads quantum integrable models and gauge-string duality and scattering amplitudes in gauge theories. Also look out for our new Insights, where we feature author- 1000000 written news items highlighting the key achievements of recent work published in 800000 the journal. We have awarded up to three Journal of Physics A Best Paper prizes 600000 to reward work that has excelled in novelty, achievement, potential impact and 400000 presentation. Please contact the journal office to make your nominations. 200000 0 We hope that you enjoy this collection. We would like to thank all of our authors 2008 2009 2010 for choosing to submit high-quality work to the journal as well as our referees for providing constructive peer review and for maintaining the quality standards of the journal. We look forward to working with you during 2011.

Mathematical papers should be clearly motivated by actual or potential application to physical phenomena. Research papers published in Journal of Physics A: Mathematical and Theoretical are catergorized into one of six subject sections: •Statistical physics •Chaotic and complex systems •Mathematical physics •Quantum mechanics and quantum information theory •Field theory and string theory •Fluid and plasma theory To be accepted for publication in the journal, papers must make significant, original and correct contributions to one or more of the topics within these sections. Journal team Our dedicated team at IOP Publishing is here to look after your work, ensuring that the whole process from submission to publication via the peer-review process and promotion is run in a satisfactory manner.
