Entropy Numbers,s-Numbers, and Eigenvalues
2018AbstractThe geometric quantities entropy numbers, approximation numbers and n-widths are defined for compact linear maps, and connections with the analytic entities eigenvalues and essential spectra discussed. The celebrated inequality of Weyl between the approximation numbers and eigenvalues is established in the general context of Lorentz sequence ...

Function Spaces, Entropy Numbers, Differential Operators
1996The distribution of the eigenvalues of differential operators has long fascinated mathematicians. Advances have shed light upon classical problems in this area, and this book presents a fresh approach, largely based upon the results of the authors. The emphasis here is on a topic of central importance in analysis, namely the relationship between i ...

Entropy-Enhanced Random Number Generation
The paper "Entropy-Enhanced Random Number Generation" presents a lightweight hybrid RNG system combining software-based pseudo-random number generators (PRNGs) with analog entropy collected using a low-cost Arduino microcontroller. By integrating analog noise sources such as light or sound with XOR and SHA-256 hashing techniques, the system achieves ...Sudnyesh Nehare, Aryan Bhad
