*The Significance of the Conformal Symmetry of String Theory”**Tiziana Vistarini, Rutgers University*

This talk summarizes the work I have been developing about the significance of conformal symmetry of string theory. I argue that this principle of invariance is not a purely formal requirement as restoring it in quantized string theory has profound consequences that could not be obtained in the presence of a conformal anomaly.

Conformal symmetry has a crucial role in explaining how general relativity can be “derived ” from quantum string theory. Indeed, quantum string theory admits emergent general relativistic spacetime by virtue of conformal symmetry. The emergence involved here is not simply in the sense that spin 2-particles – as gravitons are supposed to be – can be found in the theory, but in the strong sense that the coherent states of the corresponding field obey the Einstein field equations – they really are the gravitational field. And the physical significance of this derivation rescues string theory from the charge of being empirically incoherent.

There will be a dinner after the talk. Only the speaker’s dinner will be covered, but anybody is welcome. If you are interested, please email nyphilsci@gmail.com as soon as possible so that we can make the reservation for the appropriate number of people. If you have any other questions, please email nyphilsci@gmail.com
