A Hilbert-type inequality related to the higher derivative of cotangent function(一个关联余切函数高阶导数的Hilbert型不等式)

Zhejiang Daxue xuebao. Lixue ban
By introducing multiple parameters, and using partial fraction expansion of Cotangent function, a new Hilbert-type inequality defined in the whole plane with the constant factor related to the higher derivative of cotangent function is established. Also,

Stochastic Galerkin and Monte Carlo Methods for Parabolic Problems: Numerical Performance of Variational Matrix‐Free Approximations

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Stochastic Galerkin methods offer unexplored potential for the numerical simulation of parabolic problems with random variables, in particular if they are combined with variational discretizations of the space and time variables. Due to the high dimensionality, the solution of the arising algebraic systems do not become feasible without ...

A semi-discrete Hilbert-type inequality involving partial sums and multidimensional variable upper limit integral functions and its applications

Journal of Inequalities and Applications
By using the properties of Gamma function and the construction theorem for the semi-discrete Hilbert-type inequality with quasi-homogeneous kernel, we discuss the construction conditions for a semi-discrete Hilbert-type inequality involving partial sums ...

Symplecticity‐Preserving Prediction of Parameter‐Dependent Hamiltonian Dynamics by Generalized Kernel Interpolation

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT We extend the kernel‐based symplectic predictor introduced by Herkert et al. (2026) to a parameter‐augmented setting in which the learned flow‐map surrogate depends not only on the state, but also on additional variables such as physical parameters and macro time‐step sizes. The method uses a product kernel ansatz on a parameter and macro step

Some Local Fractional Hilbert-Type Inequalities

Fractal and Fractional, 2023
The main purpose of this paper is to prove some new local fractional Hilbert-type inequalities. Our general results are applicable to homogeneous kernels. Furthermore, the best possible constants in terms of local fractional hypergeometric function are obtained.

Contact as collective action: Positive and negative contact experiences of disadvantaged group members

Political Psychology, Volume 47, Issue 6, December 2026.
Abstract Intergroup contact programs worldwide strive to combat prejudice by promoting encounters between socially advantaged and disadvantaged groups. Despite their prevalence, little is known about how disadvantaged group members experience participation in such programs.

Refinements of local fractional Hilbert-type inequalities

Ukrains’kyi Matematychnyi Zhurnal, 2023
UDC 517.5 We study the re nements of several well-known local fractional Hilbert-type inequalities by interpolating the Lebesgue norms of the local fractional Laplace transforms of the functions involved in the inequalities. As an application, the main results are compared with some our results previously known from the literature.
