Bilinear systems with two supports: Koszul resultant matrices, eigenvalues, and eigenvectors [PDF]
International Symposium on Symbolic and Algebraic Computation, 2018 A fundamental problem in computational algebraic geometry is the computation of the resultant. A central question is when and how to compute it as the determinant of a matrix whose elements are the coefficients of the input polynomials up-to sign.

Extremal Eigenvalues and Eigenvectors of Deformed Wigner Matrices [PDF]
, 2014 We consider random matrices of the form $H = W + \lambda V$, $\lambda\in\mathbb{R}^+$, where $W$ is a real symmetric or complex Hermitian Wigner matrix of size $N$ and $V$ is a real bounded diagonal random matrix of size $N$ with i.i.d.\ entries that are

Almost Eigenvalues and Eigenvectors of Almost Mathieu Operators
Applied and Numerical Harmonic Analysis, 2015 The almost Mathieu operator is the discrete Schr\"odinger operator $H_{\alpha,\beta,\theta}$ on $\ell^2(\mathbb{Z})$ defined via $(H_{\alpha,\beta,\theta}f)(k) = f(k + 1) + f(k - 1) + \beta \cos(2\pi \alpha k + \theta) f(k)$. We derive explicit estimates

The eigenvectors-eigenvalues identity and Sun's conjectures on determinants and permanents [PDF]
Linear and multilinear algebra, 2022 In this paper, we prove several conjectures raised by Zhi-Wei Sun on determinants and permanents by the eigenvectors-eigenvalues identity recently highlighted by Denton, Parke, Tao and Zhang.

DTI Brain Template Construction Based on Gaussian Averaging
Chinese Journal of Magnetic Resonance, 2022 The tensor data of subjects are usually averaged linearly over multiple channels to obtain the tensor template. However, linear averaging ignores the vector information in the tensor. Additionally, it will render the interface between the gray matter and
