Abstract:
I will explore the constraints imposed
by conformal invariance on defects in
a conformal field theory. Correlation
function of a conformal defect with a
bulk local operator is fixed by
conformal invariance up to an overall
constant. This gives rise to the notion
of defect expansion, where the defect
itself is expanded in terms of local
operators. A correlator of two defect
operators admits a number of
conformal cross-ratios depending on
their dimensionality. I will find the
differential equation obeyed by the
conformal block and solve them in
certain special cases.
