摘要：
A generalization of Wilson loop observables for BF theories in any dimension is introduced within the Batalin-Vilkovisky framework. The expectation values of these observables are cohomology classes of the space of imbeddings of a circle. One of the resulting theories discussed in the Letter has only trivalent interactions and, irrespective of the actual dimension, looks like a three-dimensional Chern-Simons theory.
