The Spectral Distribution of Random Mixed Graphs
Axioms, 2022 In this work, we propose a random mixed graph model Gn(p(n),q(n)) that incorporates both the classical Erdős-Rényi’s random graph model and the random oriented graph model.

The feasibility and stability of large complex biological networks: a random matrix approach. [PDF]
Sci Rep, 2018 In the 70’s, Robert May demonstrated that complexity creates instability in generic models of ecological networks having random interaction matrices A. Similar random matrix models have since been applied in many disciplines.

Projecting Financial Technical Indicators Into Networks as a Tool to Build a Portfolio
IEEE Access, 2021 Using the topological structure of financial networks to build a portfolio has attracted a wide range of research interests. A similarity matrix based on the technical indicators (TIs), and a correlation matrix based on the stock returns, are used to ...

On the rank of a random binary matrix [PDF]
The Electronic Journal of Combinatorics, 2019 We study the rank of a random $n \times m$ matrix $\mathbf{A}_{n,m;k}$ with entries from $GF(2)$, and exactly $k$ unit entries in each column, the other entries being zero. The columns are chosen independently and uniformly at random from the set of all ${n \choose k}$ such columns.

Expected Values of Scalar-Valued Functions of a Complex Wishart Matrix
Mathematics, 2023 The complex Wishart distribution has ample applications in science and engineering. In this paper, we give explicit expressions for E(tr(Wh))g(tr(Wj))i and E(tr(W−h))g(tr(W−j))i, respectively, for particular values of g, h, i, j, g+h+i+j≤5, where W ...

Onset of random matrix behavior in scrambling systems [PDF]
Journal of High Energy Physics, 2018 A bstractThe fine grained energy spectrum of quantum chaotic systems is widely believed to be described by random matrix statistics. A basic scale in such a system is the energy range over which this behavior persists.

Dynamics of Correlation Structure in Stock Market
Entropy, 2014 In this paper a correction factor for Jennrich’s statistic is introduced in order to be able not only to test the stability of correlation structure, but also to identify the time windows where the instability occurs.
