Stringnet Construction Of Rcft Correlators

This book studies using stringnet models to accomplish a direct purely twodimensional approach to correlators of twodimensional rational conformal field theories. The authors obtain concise geometric expressions for the objects describing bulk and boundary fields in terms of idempotents in the cylinder category of the underlying modular fusion category comprising more general classes of fields than is standard in the literature. Combining these idempotents with Frobenius graphs on the world s
