This is the first announcement of the Workshop on Numerical Knots: Models and Simulations 8-9 June, 2011 at the Mathematical Research Centre (CRM) “Ennio De Giorgi” Scuola Normale Superiore – Pisa, Italy In conjunction with The Intensive Research Period May – July 2011 KNOTS & APPLICATIONS URL: http://www.crm.sns.it/hpp/events/event.html?id=146 Graduate students, post-docs, and junior faculty members are especially encouraged to consider participation. Since its birth, knot theory has confronted the challenges of effective representation and recognition of distinct knot types and the efficient simplification of knot representations. Now, knots endowed with physical properties of length, curvature, torsion, and thickness define spaces of such configurations whose knot types are largely unknown. Knots and other forms of entanglement occur in single polymers and in large collections, in DNA, in bacteria, in proteins, in melts and in solution. What proportion consists of knots of a given topological or physical type? What are the biological or physical implications of the structure? Are there “ideal” or “average” conformations? In addition, given an appropriate definition of knotting of “open” curves, these same questions arise in this new context. While there has been theoretical progress on some of these problems, at least in some contexts, in many cases numerical methods have been essential to gain insight if not provide answers. In this workshop we will focus on modeling open and closed chains in a variety of biological and physical contexts, on the analysis of the topological, geometric, and other properties of the modeled chains. Examples include lattice models, wormlike chains, ideal knots, shape and scale of knotting, localization, constrained environments, and knot energies with applications to DNA, proteins, viral capsids and polymer melts.

At http://listserv.utk.edu/archives/geometry.html there are many functions available, including checking the archives since November 2005, changing your e-mail address or preferences, and joining/leaving the list. If you have problems that cannot be resolved at this website, send a message to [log in to unmask] Before sending an announcement, please carefully read the following. Any announcements that are *not* about conferences (e.g. those about jobs, journals, books, etc.) will be rejected by the moderator without comment. To announce a geometry or closely related conference, send the announcement (including a conference web site if possible) to [log in to unmask] The moderator cannot edit your message; list members will receive the announcement as an e-mail from you EXACTLY as you submitted it. For example, if your submission starts with "Please post this on the geometry list" then your conference announcement will also begin with that statement. In order to keep down the volume of e-mail, only TWO announcements per conference will be approved by the moderator. The "subject" of your message should include the name of the conference and the number (first or second) of the announcement, e.g. Gauss Memorial Lectures in Geometry: Second Announcement. Please check that your announcement (especially the website) is correct. Corrections will be approved only in the most critical situations, e.g. if corrected information is not available on the website. If you send a submission from an e-mail address that is not subscribed to the geometry list then you will be sent an e-mail asking for confirmation. This feature is designed to thwart the hundreds of machine-generated spam that are sent to the list and would otherwise have to be manually blocked by the moderator. The Geometry List is sponsored and maintained by the Mathematics Department, The University of Tennessee, Knoxville.
