Query: Metastable states of spin glasses on random thin graphs   In this paper we calculate the mean number of metastable states for spin
glasses on so called random thin graphs with couplings taken from a symmetric
binary distribution $\pm J$. Thin graphs are graphs where the local
connectivity of each site is fixed to some value $c$. As in totally connected
mean field models we find that the number of metastable states increases
exponentially with the system size. Furthermore we find that the average number
of metastable states decreases as $c$ in agreement with previous studies
showing that finite connectivity corrections of order $1/c$ increase the number
of metastable states with respect to the totally connected mean field limit. We
also prove that the average number of metastable states in the limit
$c\to\infty$ is finite and converges to the average number of metastable states
in the Sherrington-Kirkpatrick model. An annealed calculation for the number of
metastable states $N_{MS}(E)$ of energy $E$ is also carried out giving a lower
bound on the ground state energy of these spin glasses. For small $c$ one may
obtain analytic expressions for $<N_{MS}(E)>$.
