+We can finally write the complexity with fixed minimum eigenvalue $\lambda^*$ as
 \begin{equation}
   \Sigma_{\lambda^*}(E,\mu)=\operatorname{extremum}_{\hat\beta,r,d,g,y_0,\Delta z,\hat\lambda}\mathcal S_\infty

+Note that unlike the previous two examples, the effective action in this case
+does not split into two largely independent pieces, one relating to the
+eigenvalue problem and one relating to the ordinary complexity. Instead, the
+order parameters related to the eigenvalue problem are mixed throughout the
+effective action with those of the ordinary complexity. This is a signal of the
+fact that the sum of squares problem is not Gaussian, while the previous two
+examples are. In all non-Gaussian problems, conditioning on properties of the
+Hessian cannot be done independently from the complexity, and the method
+introduced in this paper becomes necessary.

+Fig.~\ref{fig:ls.complexity} shows the marginal complexity in a sum-of-squares
+model with $\alpha=\frac32$ and $f(q)=q^2+q^3$. Also shown is the dominant
+complexity computed in Appendix~\ref{sec:dominant.complexity}. As the figure
+demonstrates, the range of energies at which marginal minima are found can
+differ significantly from those implied by the dominant complexity, with the
+lowest energy significantly higher than the ground state and the highest energy
+significantly higher than the threshold.
