We begin with a brief review of measures such as entanglement entropy, relative entropy and techniques to evaluate them in 2d CFT. We then study the properties of these measures when the theory or the state on which these measures are evaluated are deformed by the symmetries of the theory. The symmetries we focus are the Virasoro symmetries and higher spin symmetries. We present 2 situations for which the deformations result in universal corrections to the information theoretic measures.
