Invertibility Conditions for Second-Order Differential Operators in the Space of Continuous Bounded Functions

Autor: L. Yu. Kabantsova, A. G. Baskakov, T. I. Smagina

Publikováno v: Differential Equations. 54:285-294

We prove the invertibility of second-order differential operators with constant operator coefficients acting on the Banach space of bounded continuous functions on the real line under the condition that they are uniformly injective (in particular, le

Publikováno v: IOP Conference Series: Earth and Environmental Science. 941:012036

The paper presents the results of the scientific and economic experiment for the evaluation of the influence of the energy supplement included in the diet of lactating cows of the Brown Swiss breed. During the research period, all animals were kept i

Second-order linear differential equations in a Banach space and splitting operators

Autor: T. I. Smagina, Anatoly Grigorievich Baskakov, T. K. Katsaran

Publikováno v: Russian Mathematics. 61:32-43

We consider a second-order linear differential equation whose coefficients are bounded operators acting in a complex Banach space. For this equation with a bounded right-hand side, we study the question on the existence of solutions which are bounded

Linear differential operators and operator matrices of the second order

Autor: I. D. Kostrub, A. G. Baskakov, T. I. Smagina, L. Yu. Kabantsova

Publikováno v: Differential Equations. 53:8-17

Linear differential operators (equations) of the second order in Banach spaces of vector functions defined on the entire real axis are studied. Conditions of their invertibility are given. The main results are based on putting a differential operator

ECOLOGICAL ATLAS OF ROSTOV OBLAST: STRUCTURE, CONTENT, AND METHODS OF ASSESSMENT

Autor: L. N. Larina, Ye. M. Tsvylev, M. I. Kizitskiy, V. Ye. Zakrutkin, T. A. Smagina, M. M. Ryshkov, A. A. Kozhin, D. Yu. Shishkina

Publikováno v: Mapping Sciences and Remote Sensing. 36:202-214

A method for geoecological mapping at a scale of 1:500,000 was developed and tested. All 104 atlas maps were compiled by applying the same principles—use of the administrative district (rayon) as the effective statistical unit and a scale-unit (int
