abstract

We reconsider the one loop divergence of ${\cal N}=8$ supergravity in four dimensions. We compute the finite effective potential of ${\cal N}=8$ anti-deSitter supergravity and interpret it as logarithmic running of the cosmological constant. We find that quantum inequivalence between fields that are classically dual is due to boundary modes in AdS$_4$. Some subtleties are traced to the difference between the Euler characteristic of global and thermal AdS$_4$.

    The bulk one-loop partition function of JT gravity reproduces the SYK result -3/2 log beta, with the logarithmic contribution coming entirely from quadratic holomorphic differentials.
