Partial Derivative Approach to the Integral Transform for the Function Space in the Banach Algebra [PDF]

open access: yesEntropy, 2020
We investigate some relationships among the integral transform, the function space integral and the first variation of the partial derivative approach in the Banach algebra defined on the function space.

Partial Soft Derivative

open access: yesCommunications in Advanced Mathematical Sciences
The concept of soft derivative, introduced by Molodtsov in 1999, is one of the fundamental concepts in soft analysis. The handled paper defines partial soft derivative and studies some of its basic properties, such as the relation between partial soft ...

In creatinine kinetics, the glomerular filtration rate always moves the serum creatinine in the opposite direction

open access: yesPhysiological Reports, 2021
Introduction When the serum [creatinine] is changing, creatinine kinetics can still gauge the kidney function, and knowing the kinetic glomerular filtration rate (GFR) helps doctors take care of patients with renal failure.

The Riemann method for equations with a dominant partial derivative (A Review) [PDF]

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2021
This review article is devoted to a class of linear equations with a dominant (leading) partial derivative of the form \((D+M)u=f\), where \(Du\) is a mixed partial derivative, and \(M\) is a linear differential operator containing the derivatives of the

On the differentiation of a composite function with a generalized vector argument on homogeneous time scales; pp. 309–322 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2017
The paper proves a theorem on the differentiation of a composite function with a generalized vector argument. The theorem is formulated in terms of the delta derivative, which in the case of homogeneous time scales incorporates both the ordinary ...

Properties of power series of analytic in a bidisc functions of bounded $\mathbf{L}$-index in joint variables

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2017
We generalized some criteria of boundedness of $\mathbf{L}$-index in joint variables for analytic in a bidisc functions, where $\mathbf{L}(z)=(l_1(z_1,z_2),$ $l_{2}(z_1,z_2)),$ $l_j:\mathbb{D}^2\to \mathbb{R}_+$ is a continuous function, $j\in\{1,2\},$

Theorem on the differentiation of a composite function with a vector argument; pp. 195–200 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2010
The paper provides a theorem on the differentiation of a composite function with a vector argument. The theorem shows how the partial derivative of the total derivative of the composite function can be expressed through the total derivative of the ...
