We study the topology of smectic defects in two and three dimensions. We give a topological classification of smectic point defects and disclination lines in three dimensions. In addition we describe the combination rules for smectic point defects in two and three dimensions, showing how the broken translational symmetry of the smectic confers a path dependence on the result of defect addition.

The Leverhulme Trust invites applications for its visiting professorships. These enable UK institutions to host distinguished researchers from overseas, primarily to enhance the skills of academic staff or students at the host institution. Visiting professors may also wish to use the opportunity to further their own academic interests and visit more than one UK institution.

Any field of research is eligible, excluding studies of disease, illness and disabilities in humans and animals, and research that is intended to inform clinical practice or the development of medical applications. Applications must be made by a member of academic staff, based in a UK university or other HEI, who will be responsible for co-ordinating the visit. Priority is given to new or recent collaborative ventures.

Funding is worth between 拢10,000 and 拢150,000 and covers maintenance, travel expenses and research costs of visits that last between three and 12 months. Travel within the UK, laboratory consumables and essential technical assistance may also be covered.
