In summary: This just appeared todayIn summary, John C. Baez and Alejandro Perez show that the coupling to point particles that is natural in three dimensions generalizes in a direct way to BF theory in d dimensions coupled to (d-3)-branes. In the resulting model, the connection is flat except along the membrane world-sheet, where it has a conical singularity whose strength is proportional to the membrane tension. As a step towards canonically quantizing these models, they show that a basis of kinematical states is given by 'membrane spin networks', which are spin networks equipped with extra data where their edges end on a brane.

Dearly Missed

BTW Alejandro Perez will be in Utrecht in a few days giving a talk on the subject of this paper

the current seminar schedule is here
