Algebraic Structures in Euclidean and Minkowskian Two-Dimensional Conformal Field Theory
Liang Kong, Ingo Runkel
We review how modular categories, and commutative and non-commutative Frobenius algebras arise in rational conformal field theory. For Euclidean CFT we use an approach based on sew…
Topological defects for the free boson CFT
Jürgen Fuchs, Matthias R. Gaberdiel, Ingo Runkel +1
Two different conformal field theories can be joined together along a defect line. We study such defects for the case where the conformal field theories on either side are single f…
Duality and defects in rational conformal field theory
Jürg Fröhlich, Jürgen Fuchs, Ingo Runkel +1
We study topological defect lines in two-dimensional rational conformal field theory. Continuous variation of the location of such a defect does not change the value of a correlato…
Picard groups in rational conformal field theory
Jürg Fröhlich, Jürgen Fuchs, Ingo Runkel +1
Algebra and representation theory in modular tensor categories can be combined with tools from topological field theory to obtain a deeper understanding of rational conformal field…
Renormalisation group flows of boundary theories
K. Graham, I. Runkel, G. M. T. Watts
We review recent developments in the theory of renormalisation group flows in minimal models with boundaries. Among these, we discuss in particular the perturbative calculations of…
