On moments of the derivative of CUE characteristic polynomials and the Riemann zeta function
Journal of the London Mathematical Society, Volume 113, Issue 3, March 2026.Abstract We study the derivative of the characteristic polynomial of N×N$N \times N$ Haar‐distributed unitary matrices. We obtain new explicit formulae for complex‐valued moments when the spectral variable is inside the unit disc, in the limit N→∞$N \rightarrow \infty$.

Hankel Operators and the Dixmier Trace on Strictly Pseudoconvex Domains [PDF]
, 2010 Generalizing earlier results for the disc and the ball, we give a formula for the Dixmier trace of the product of 2(n) Hankel operators on Bergman spaces of strictly pseudoconvex domains in C-n.

Steady‐State Spread Bounds for Graph Diffusion via Laplacian Regularisation in Networked Systems
IET Networks, Volume 15, Issue 1, January/December 2026.We study how an engineered initial pattern on a fixed network blurs under linear diffusion and provide a steady‐state upper bound on the resulting deviation. The bound cleanly separates an unavoidable floor set by network connectivity and diffusion strength from a design‐controlled term that shrinks when the initial pattern is smoothed with a graph ...

Bergman 공간 위의 Toeplitz 작용소에 관한 연구 [PDF]
, 1994 학위논문(박사) - 한국과학기술원 : 수학과(복소해석학전공), 1994.2, [ 94 p. ; ]In this thesis, we are concerned with Toeplitz operators acting on the Bergman spaces of the unit ball in the n-dimensional complex space $C^n$.

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.Core approach: hybrid model combining wake dynamics, spectral clustering and adaptive neighbourhood selection. Methodology: spatial decoupling → representative turbine identification → feature aggregation via memory network. Outcome: enhanced prediction accuracy validated by real‐data comparisons, addressing spatial correlation challenges in wind farms.

Design and Optimization of Finite Alphabet Waveforms for Multiple‐Antenna Radar Covariance Matching
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This article propose a novel method for finite‐alphabet waveform generation based on constrained matrix decomposition. It also expands theoretical feasibility bounds for generating covariance matrices with binary waveforms, proves that matrices from autoregressive processes are always realizable and introduces an optimal adjustment procedure for ...

Asymptotic Correlations in Gapped and Critical Topological Phases of 1D Quantum Systems [PDF]
, 2019 Topological phases protected by symmetry can occur in gapped and—surprisingly—in critical systems. We consider non-interacting fermions in one dimension with spinless time-reversal symmetry.

On the minimum modulus of dual truncated Toeplitz operators
This article provides a systematic investigation of the minimum modulus of dual truncated Toeplitz operators (DTTOs) $D_φ$ acting on the orthogonal complement of the model space $\mathcal{K}_u^{\perp}$, where $u$ is a nonconstant inner function and $φ\in L^\infty(\T)$.
