Operator bases, S-matrices, and their partition functions [PDF]

open access: yesJournal of High Energy Physics, 2017
Relativistic quantum systems that admit scattering experiments are quantitatively described by effective field theories, where S-matrix kinematics and symmetry considerations are encoded in the operator spectrum of the EFT.

A More Accurate Half-Discrete Multidimensional Hilbert-Type Inequality Involving One Multiple Upper Limit Function

open access: yesAxioms, 2023
By means of the weight functions, the idea of introduced parameters, using the transfer formula and Hermite–Hadamard’s inequality, a more accurate half-discrete multidimensional Hilbert-type inequality with the homogeneous kernel as 1(x+||k−ξ||α)λ(x,λ>0)

On a New Extended Hardy–Hilbert’s Inequality with Parameters

open access: yesMathematics, 2020
In this paper, by introducing parameters and weight functions, with the help of the Euler−Maclaurin summation formula, we establish the extension of Hardy−Hilbert’s inequality and its equivalent forms.

New Schweizer Sklar Norm Picture Fuzzy Operator and Decision Application [PDF]

open access: yesJisuanji gongcheng, 2023
Existing picture fuzzy operational laws do not satisfy the closure and picture fuzzy aggregation operators, mostly aggregating the evaluation information through a single operator, which interferes with the comprehensive consideration of the relationship

Spectral properties of singular Sturm-Liouville operators with indefinite weight sgn x [PDF]

open access: yes, 2007
We consider a singular Sturm-Liouville expression with the indefinite weight sgn x. To this expression there is naturally a self-adjoint operator in some Krein space associated.
