On moments of complex Wishart and complex inverse Wishart distributed matrices

This paper addresses the calculation of moments of complex Wishart and complex inverse Wishart distributed random matrices. Complex Wishart and complex inverse Wishart distributed random matrices are used in applications like radar, sonar, or seismics in order to model the statistical properties of complex sample covariance matrices and complex inverse sample covariance matrices, respectively. ...

On absolute moments of characteristic polynomials of a certain class of complex random matrices

Integer moments of the spectral determinant |det(zI−W )|2 of complex random matrices W are obtained in terms of the characteristic polynomial of the Hermitian matrix WW ∗ for the class of matrices W = AU where A is a given matrix and U is random unitary. This work is motivated by studies of complex eigenvalues of random matrices and potential applications of the obtained results in this context...

Comparative Study of Random Matrices Capability in Uncertainty Detection of Pier’s Dynamics

Because of random nature of many dependent variables in coastal engineering, treatment of effective parameters is generally associated with uncertainty. Numerical models are often used for dynamic analysis of complex structures, including mechanical systems. Furthermore, deterministic models are not sufficient for exact anticipation of structure’s dynamic response, but probabilistic models...

Eigenvalues and Condition Numbers of Complex Random Matrices

In this paper, the distributions of the largest and smallest eigenvalues of complex Wishart matrices and the condition number of complex Gaussian random matrices are derived. These distributions are represented by complex hypergeometric functions of matrix arguments, which can be expressed in terms of complex zonal polynomials. Several results are derived on complex hypergeometric functions and...

Several Applications of the Moment Method in Band Random Matrix Model

Random matrix theory (RMT) has wide applications in various areas of science. It can be traced back to sample covariance matrices studied by J. Wishart in data analysis in 1920s1930s. In 1951, E. Wigner associated the energy levels of heavy-nuclei atoms with Hermitian matrices with i.i.d entries. To simplify the complex Hamiltonians of heavy-nuclei atoms, Wigner introduced the ensemble of real ...
