Some inequalities for operator (p,h)-convex functions

Trung Hoa Dinh, Khue TB Vo

Let $p$ be a positive number and $h$ a function on $R^{+}$ satisfying $h (x y) \geq h (x) h (y)$ for any $x, y \in R^{+}$ . A non-negative continuous function $f$ on $K (\s…

Nearby Early-Type Galactic Nuclei at High Resolution: Dynamical Black Hole and Nuclear Star Cluster Mass Measurements

Dieu D. Nguyen, Anil C. Seth, Nadine Neumayer +12

We present a detailed study of the nuclear star clusters (NSCs) and massive black holes (BHs) of four of the nearest low-mass early-type galaxies: M32, NGC205, NGC5012, and NGC5206…

On the determination of the Singer transfer

Nguyen Sum

Let $P_{k}$ be the graded polynomial algebra $F_{2} [x_{1}, x_{2}, \dots, x_{k}]$ with the degree of each generator $x_{i}$ being 1, where $F_{2}$ denote the prime field of two ele…

Finite determinacy of matrices and ideals

Gert-Martin Greuel, Thuy Huong Pham

The main aim of this paper is to characterize ideals I in the power series ring R=K[[x1,...,xs]] that are finitely determined up to contact equivalence by proving that this is the…

Hausdorff operators on holomorphic Hardy spaces and applications

Ha Duy Hung, Luong Dang Ky, Thai Thuan Quang

The aim of this paper is to characterize the nonnegative functions $φ$ defined on $(0, \infty)$ for which the Hausdorff operator $$\mathscr H_φf(z)= \int_0^\infty f\left(\frac{z}{t}…
