+Load the class zbMATH via
+
+    \documentclass{zbMATH}
+
+Use the commands
+    
+    \title{<title of the reviewed article>}
+    \author{<authors of the reviewed article>}
+
+to set the title and author information of the article under review. 
+The title and footer of your review are generated via
+
+    \maketitle
+    \makefooter
+ 
+Afterwards, add the text of your review. 
+At the end of your review you can add your name using the macro
+
+    \reviewer{<Your Name>}
+
+Optionally, you can add MSC Classes and keywords using 
+
+    \msc{<MSC Classes>}
+    \keywords{<keywords>}
+
+where MSC classes are separated by space and keywords are separated by a semicolon ';'.

+% text of the review
+This paper is concerned with the convergence of empirical spectral distributions (ESD) of random matrices, both in the sense of convergence in probability and in the almost sure sense.
+
+
+Recall that for each \(n\in {\mathbb N}\), if \(F_n\) is a random variable taking values in some Hausdorff topological space \(X\) and let \(F\in X\), then we say that
+{\parindent5mm
+\begin{itemize}
+    \item[1)] \(F_n\) converges in probability to \(F\) if \(\lim_{n\to \infty} P(F_n\in V) = 1\) for every neighborhood \(V\) of \(F\).
+    \item[2)] \(F_n\) converges almost surely to \(F\) if \(P(\lim _{n\to \infty} F_n=F) = 1\).
+\end{itemize}}
+A fundamental problem in the theory of random matrices is to determine the limiting distribution of the ESD of a random matrix ensemble (either in probability or in the almost sure sense) as the size of the random matrix tends to infinity. The universality phenomenon (a well-known intuition) asserts that the limiting distribution should not depend on the particular distribution of the entries. In the 1950s Wigner proved that the ESD of an \(n\times n\) Hermitian matrix with (upper diagonal) entries being i.i.d. Gaussian random variables converge to the semicircle law \(F\) with density 
+\[
+\rho(x)=\begin{cases} \frac 1{2\pi} \sqrt {4-x^2}, &|x|\leq 2\\ 0 &|x|>0 \end{cases}
+\]
+Wigner's result was then extended in different forms and one of them is:
+
+Theorem 1.3. Let \(A_n\) be the \(n \times n\) Hermitian random matrix whose upper diagonal entries are i.i.d. complex random variables with mean \(0\) and variance \(1\). The ESD of \(\frac 1{\sqrt n}A_n\) then converges (in both convergence modes) to the semicircle distribution.
+
+ The well-known circular law conjecture asserts that Theorem 1.3 deals with the non-Hermitian matrices: 
+
+Conjecture 1.4. (Circular law conjecture) Let \(A_n\) be the \(n \times n\) random matrix whose entries are i.i.d. complex random variables with mean \(0\) and variance \(1\). The ESD of \(\frac 1{\sqrt n}A_n\) then converges (in both convergence modes) to the uniform distribution on the unit disk.
+
+Works towards the circular law conjecture have been done by many authors including Mehta, Edelman, Girko, Bai, Götze and Tikhomirov, Pan and Zhou and the present authors (see the references) under some assumptions on the distribution. For example, Mehta (complex Gaussian distribution), Edelman (real Gaussian distribution).
+
+The authors prove the above conjecture (Theorem 1.10). They first establish some universality principles (Theorem 1.5 and Corollary 1.8). It turns out the limit distribution of the ESD of a random matrix ensemble \(A_n\) depends only on the mean and variance of its entries, under a mild size condition on the mean \({\mathbf E}A_n\) and under the assumption that the matrix \(A_n-{\mathbf E}A_n\) has i.i.d. entries. Because of Corollary 1.8, the proof is reduced to the case where the entries are Gaussian (Lindeberg trick). Thus from Mehta's result the circular law conjecture follows.
+
+As a related result, they show how laws for this ESD follow from laws for the singular value distribution of \(\frac 1{\sqrt n}A_n-zI\) for complex \(z\) (see Theorem 1.15). Other interesting results are obtained.
+
+Appendix A reviews some matrix inequalities and Appendix B is authored by M. Krishnapur.
+
+Some typos and comments on Appendix A: Lemma A.2 ``generalized eigenvalues'' should be ``eigenvalues''. In the proof, ``orthogonal \(Q\)'' should be ``unitary \(Q\)'' (indeed the proof follows directly from Schur's triangularization theorem). In the proof of Lemma A.4, \(X_j\), \(W_j\) should be \(X_j^*\), \(W_j^*\) respectively. Indeed the majorization between the vectors \((\sigma_1(A)^{-1},\dots , \sigma_{n'}(A)^{-2})\) and \((\text{dist} (X_1,W_1)^{-2}, \dots, \text{dist} (X_{n'},W_{n'})^{-2})\) holds by applying Schur's result on the positive definite matrix \((AA^*)^{-1}\).
