CECIL KING 20 TRAVEL SCHOLARSHIP 21

The London Mathematical Society annually awards a £5,000 Cecil King Travel Scholarship in Mathematics, to a young mathematician of out- standing promise. The Scholarship is awarded to support a period of study or research abroad, typically for a period of three months. Study or research in all areas of mathematics is eligible for the award.

The award is competitive and based on a written proposal describing the intended programme of study or research abroad, and the ben- efits to be gained from such a visit. A shortlist of applicants will be selected for an interview during which they will be expected to make a short presentation on their proposal.

Applicants should normally be nationals of the UK or Republic of Ire- land, either registered for or having completed a doctoral degree within 12 months of the closing date.

Applications should be made using the form available on the Society's website (www.lms.ac.uk/content/cecil-king-travel-scholarship) or by contacting [email protected]. The closing date for applications is Friday 8 March 2013. It is expected that interviews will take place in London in late April or early May.

LIQUID CRYSTAL DEFECTS AND THEIR GEOMETRY, ACTIVE AND SOLID LIQUID CRYSTALS, AND RELATED SYSTEMS 24 - 28 June 2013

in association with the Newton Institute programme The Mathematics of Liquid Crystals (7 January –5 July 2013)

Workshop organisers: Oleg Lavrentovich (Kent State University), Tom Lubensky (Uni- versity of Pennsylvania), Antonio de Simone (SISSA) and Mark Warner .

26 Typically described by their well-ordered structures, liquid crystal phases were first 27 identified and even named by their topological defects. The rich interplay between geometry, topology, and optics is ubiquitous through all liquid crystals. We will discuss their characterisation, and also their essential appearance in complex systems such as colloidal liquid crystals and in blue phases. Their exploitation in templating complex structures and their special character in non-simple spaces (such as those with Gaussian curvature) will also be examined. In parallel, the workshop is concerned with solid liquid crystals, both elastomers where the director remains mobile, and glasses where the di- rector is pinned to the material frame. The unique mechanics of solid liquid crystals, and its connection with techniques of quasi-convexification first exploited in Martensites, is an active area of research. Mechanics connects with the defects theme since topological defects in LC solids, on illumination or temperature change, cause changes in Gaussian curvature or topology. These consequences, and those when nematics become active will also be explored.

This workshop will bring together experts in all the above fields, to compare and con- trast the various them, to discuss topical and future problems and methods of their solution, and to explore possible applications.

Further information and application forms are available from the website at www.newton.ac.uk/programmes/MLC/mlcw04.shtml.
