Particularly, I am dealing with Erdős–Rényi random 𝐺(𝑛,𝑝), so the expected Laplacian matrix of 𝐺(𝑛,𝑝) is 𝑝(𝐽𝑛−𝐼𝑛), where 𝐽𝑛 and 𝐼𝑛 are one and identity matrices, respectively.
In addition,if the distribution (unsure, but might be power law) of the eigenvalues of Laplacian matrix of the graph 𝐺(𝑛,𝑝) is known, then it seems to me that expected value of the eigenvalues has some closed form formula depending on 𝑛 and 𝑝 in the asymptotic case.
