Subadditivity of Matrix phi-Entropy and Concentration of Random Matrices [PDF]
, 2013 Matrix concentration inequalities provide a direct way to bound the typical spectral norm of a random matrix. The methods for establishing these results often parallel classical arguments, such as the Laplace transform method. This work develops a matrix

The Schur Multiplicative and Harmonic Convexities for Three Classes of Symmetric Functions
Journal of Function Spaces, 2018 We investigate the Schur harmonic convexity for two classes of symmetric functions and the Schur multiplicative convexity for a class of symmetric functions by using a new method and generalizing previous result.

Fourier multiplier theorems involving type and cotype [PDF]
, 2017 In this paper we develop the theory of Fourier multiplier operators $T_{m}:L^{p}(\mathbb{R}^{d};X)\to L^{q}(\mathbb{R}^{d};Y)$, for Banach spaces $X$ and $Y$, $1\leq p\leq q\leq \infty$ and $m:\mathbb{R}^d\to \mathcal{L}(X,Y)$ an operator-valued symbol ...

Petrović‐Type Inequalities for Harmonic h‐convex Functions
Journal of Function Spaces, Volume 2020, Issue 1, 2020., 2020 In the article, we establish several Petrović‐type inequalities for the harmonic h‐convex (concave) function if h is a submultiplicative (super‐multiplicative) function, provide some new majorizaton type inequalities for harmonic convex function, and prove the superadditivity, subadditivity, linearity, and monotonicity properties for the functionals ...

A Reverse Analytic Inequality for the Elementary Symmetric Function with Applications
Journal of Applied Mathematics, 2013 We give a reverse inequality involving the elementary symmetric function by use of the Schur harmonic convexity theory. As applications, several new analytic inequalities for the n-dimensional simplex are established.

An Algebraic Perspective on Multivariate Tight Wavelet Frames. II
, 2013 Continuing our recent work we study polynomial masks of multivariate tight wavelet frames from two additional and complementary points of view: convexity and system theory.

Wehrl entropy, Lieb conjecture and entanglement monotones
, 2003 We propose to quantify the entanglement of pure states of $N \times N$ bipartite quantum system by defining its Husimi distribution with respect to $SU(N)\times SU(N)$ coherent states.

Optimal Tx-BF for MIMO SC-FDE Systems
, 2013 Transmit beamforming (Tx-BF) for multiple-input multiple-output (MIMO) channels is an effective means to improve system performance. In frequency-selective channels, Tx-BF can be implemented in combination with single-carrier frequency-domain ...

International Journal of Robust and Nonlinear Control, Volume 36, Issue 5, Page 2907-2926, 25 March 2026.ABSTRACT This study presents a novel Distributed Robust Adaptive Model Predictive Control (DRAMPC) for tracking in multi‐agent systems. The framework is designed to work with dynamically coupled subsystems and limited communication, which is restricted to local neighborhoods.
