Order, 2017 A function \(f\) from the \(n\)-th power of \(A\) to \(B\) is called a minor of another function \(g\) from the \(m\)-th power of \(A\) to \(B\), or \(g\) is a major of \(f\), if \(f\) can be obtained from \(g\) by identification of arguments, permutation of arguments, or introduction or deletion of inessential arguments. The minor relation constitutes

Majorization and Spherical Functions [PDF]
International Mathematics Research Notices, 2021 Abstract In this paper, we generalize a result of Cuttler, Greene, Skandera, and Sra that characterizes the majorization order on Young diagrams in terms of nonnegative specializations of Schur polynomials. More precisely, we introduce a generalized notion of majorization associated to an arbitrary crystallographic root system $\Phi ...

The functional Breuer–Major theorem [PDF]
Probability Theory and Related Fields, 2019 Let $X=\{ X_n\}_{n\in \mathbb{Z}}$ be zero-mean stationary Gaussian sequence of random variables with covariance function $ $ satisfying $ (0)=1$. Let $ :\mathbb{R}\to\mathbb{R}$ be a function such that $E[ (X_0)^2]2$.

Thyroid function in thalassaemia major. [PDF]
Archives of Disease in Childhood, 1980 Serum concentrations of T4, T3, rT3, and TSH were measured by radioimmunoassay in 45 patients suffering from beta-thalassaemia. A TRH stimulation test was performed and the binding capacity of TBG and TBPA for T3 and T4 measured by reverse flow zone electrophoresis in a group of these patients.

Researches in Mathematics, 2019 Estimates above and estimates below have been obtained for Kolmogorov, linear and Bernshtein average $\nu$-widths on the classes of functions $W^r (\omega^w, \Psi)$, where $r \in \mathbb{N}$, $\omega^w(f)$ is the generalized characteristic of smoothness ...

STABILITY-PRESERVING PERTURBATION OF THE MAXIMAL TERMS OF DIRICHLET SERIES
Проблемы анализа, 2022 We study stability of the maximal term of the Dirichlet series with positive exponents, the sum of which is an entire function. This problem is of interest, because the Leont’ev formulas for coefficients calculated using a biorthogonal system of ...

Isolated singularities of mappings with the inverse Poletsky inequality
Математичні Студії, 2021 The manuscript is devoted to the study of mappings with finite distortion, which have been actively studied recently. We consider mappings satisfying the inverse Poletsky inequality, which can have branch points.

Cognitive function in major depression
Journal of Affective Disorders, 1992 Forty patients with a major depressive episode were divided into equal endogenous and neurotic sub-groups using the Newcastle scale. They were all rated on the 17-item Hamilton scale and with a variety of neuropsychological tests. They were compared with 20 age- and education-matched control subjects.

On one rational integral operator of Fourier – Chebyshev type and approximation of Markov functions
Журнал Белорусского государственного университета: Математика, информатика, 2020 The purpose of this paper is to construct an integral rational Fourier operator based on the system of Chebyshev – Markov rational functions and to study its approximation properties on classes of Markov functions. In the introduction the main results of
