Abstract

We discuss a possible relation between singletons in AdS space and logarithmic conformal field theories at the boundary of AdS. It is shown that the bulk Lagrangian for singleton field (singleton dipole) induces on the boundary the two-point correlation function for logarithmic pair. Bulk interpretation of mixing between logarithmic operator D and zero mode operator C under the scale transformation is discussed as well as some other issues.
