A discrete Hilbert-type inequality in the whole plane
Journal of Inequalities and Applications, 2016 By the use of weight coefficients and technique of real analysis, a discrete Hilbert-type inequality in the whole plane with multi-parameters and a best possible constant factor is given.

The Krein-von Neumann extension of a regular even order quasi-differential operator [PDF]
Opuscula Mathematica, 2021 We characterize by boundary conditions the Krein-von Neumann extension of a strictly positive minimal operator corresponding to a regular even order quasi-differential expression of Shin-Zettl type.

Operational semantics: Concepts and their expression [PDF]
Information Processing Letters, 2003 One of the earliest approaches to giving formal semantics for programming languages was ``operational semantics''. Enthusiasm for this approach has waxed and waned. The main objective of this paper is to tease apart some concepts involved in writing such operational descriptions and (as separately as possible) to discuss useful notations.

Boundedly solvable degenerate differential operators for first order
Universal Journal of Mathematics and Applications, 2018 Using the methods of operator theory all boundedly solvable extensions of the minimal operator generated by degenerated type differential-operators expression in the weighted Hilbert space of vector-functions in finite interval in terms of boundary ...

Transformation operators for impedance Sturm–Liouville operators on the line
Математичні Студії, 2023 In the Hilbert space $H:=L_2(\mathbb{R})$, we consider the impedance Sturm--Liouville operator $T:H\to H$ generated by the differential expression $ -p\frac{d}{dx}{\frac1{p^2}}\frac{d}{dx}p$, where the function $p:\mathbb{R}\to\mathbb{R}_+$ is of ...

Krein-von Neumann extension of an even order differential operator on a finite interval [PDF]
Opuscula Mathematica, 2018 We describe the Krein-von Neumann extension of minimal operator associated with the expression \(\mathcal{A}:=(-1)^n\frac{d^{2n}}{dx^{2n}}\) on a finite interval \((a,b)\) in terms of boundary conditions. All non-negative extensions of the operator \(A\)

Electron Broadening Operator Including Penetrating Collisions for Hydrogen
Atoms, 2020 The expression of the electron broadening operator including the effect of penetrating collisions, i.e., for which the incoming electron enters the extent of bound-electron wave-functions, is rather complicated, even for hydrogen.

The Veneziano amplitude via mostly BRST exact operator
Nuclear Physics B, 2022 The Veneziano amplitude is derived from fixing one degree of freedom of PSL(2,R) symmetry by the insertion of a mostly BRST exact operator. Evaluating the five-point function which consists of four open string tachyons and this gauge fixing operator, we ...
