We review recent results obtained for the eigenvalue statistics of n x
n Hermitian (real symmetric) random matrices with nonunitary (nonorth
ogonal) invariant probability distributions. Most of the paper is devo
ted to the normalized counting measure of eigenvalues (NCM). We descri
be formulae for the nonrandom limit form (known as the integrated dens
ity of states (IDS)) of this random measure corresponding to a variety
of the random matrix ensembles and obtained by an unique method, base
d on the study of the Stieltjes transform of the NCM. We mention also
results on the 1/n corrections to the IDS and to more complex statisti
cal characteristics of the eigenvalue distribution obtained by the sam
e method.
