On the asymptotic behavior of a log gas in the bulk scaling limit in the presence of a varying external potential II

Abstract

In this paper we continue our analysis \cite{BDIK} of the determinant $\det (I-\gamma K_s),\gamma \in (0,1)$ where $K_s$ is the trace class operator acting in $L^2(-1,1)$ with kernel $K_s(\lambda ,\mu )=\frac{\sin s(\lambda -\mu )}{\pi (\lambda -\mu )}$. In \cite{BDIK} various key asymptotic results were stated and utilized, but without proof: Here we provide the proofs (see Theorem 1.2 and Proposition 1.3 below).
