Non-Linear Spectrum-Preserving Maps

Bulletin of the London Mathematical Society, 2000
Summary: Let \({\mathcal M}_n\) denote the space of complex \(n\times n\) matrices, and let \(\Omega_n\) denote the spectral unit ball of \({\mathcal M}_n\), namely the set of matrices in \({\mathcal M}_n\) whose eigenvalues lie within the open unit disc. As a step towards the eventual classification of the holomorphic automorphisms of \(\Omega_n\), we

On Almost Interval Preserving Linear Operators

Siberian Mathematical Journal, 2022
In this paper, the author obtained an analogous description of \(AM\)-compact and compact almost interval preserving linear operators in quasi-Banach lattices. She established one structural property of almost interval preserving operators which is in its own right.

Discrete Locally-Linear Preserving Hashing

2018 25th IEEE International Conference on Image Processing (ICIP), 2018
Recently, hashing has attracted considerable attention for nearest neighbor search due to its fast query speed and low storage cost. However, existing unsupervised hashing algorithms have two problems in common. Firstly, the widely utilized anchor graph construction algorithm has inherent limitations in local weight estimation.

Distance preserving linear feature selection

Pattern Recognition, 1979
Abstract A new method for linear feature selection is described which has as its underlying theme the preservation of actual distances between training data points in the lower dimensional space. Comparison with existing methodology places the method closer to the principle components or Karhunen- Loeve approach than to methods based on an approach ...

Eigenvectors of Order-Preserving Linear Operators

Journal of the London Mathematical Society, 1998
Summary: Suppose that \(K\) is a closed, total cone in a real Banach space \(X\), that \(A: X\to X\) is a bounded linear operator which maps \(K\) into itself, and that \(A'\) denotes the Banach space adjoint of \(A\). Assume that \(r\), the spectral radius of \(A\), is positive, and that there exist \(x_0\neq 0\) and \(m\geq 1\) with \(A^m(x_0)= r^m ...
