|A short introduction will be given to simple extensions of conformal invariance, which can be used to describe situations, where the two-point functions of a critical system also contain
additional logarithmic factors.
In particular, we shall comment on how such a construction can be extended to variants of conformal symmetry which might be useful in the description of non-equilibrium critical points, as they arise for example in ageing phenomena far from equilibrium. As an example, we shall consider critical directed percolation.
