On Strongly Continuous Resolving Families of Operators for Fractional Distributed Order Equations [PDF]
Fractal and Fractional, 2021 The aim of this work is to find by the methods of the Laplace transform the conditions for the existence of a strongly continuous resolving family of operators for a linear homogeneous equation in a Banach space with the distributed Gerasimov–Caputo ...

Properties of Topologies for the Continuous Representability of All Weakly Continuous Preorders [PDF]
Mathematics, 2023 We investigate properties of strongly useful topologies, i.e., topologies with respect to which every weakly continuous preorder admits a continuous order-preserving function.

Rocky Mountain Journal of Mathematics, 2017 In this article, we consider nonlinear elliptic fourth-order equations with the monotone principal part satisfying the common growth and coerciveness conditions for Sobolev space $W^{2,p}(\Omega )$, $\Omega \subset \mathbb {R}^{n}$. It is supposed that the lower-order term of the equations admits arbitrary growth with respect to an unknown function and

Statistical Ergodic Theorem in Symmetric Spaces for Infinite Measures
Современная математика: Фундаментальные направления, 2021 Let (Ω,μ) be a measurable space with σ -finite continuous measure, μ(Ω)=∞. A linear operator T:L1(Ω)+L∞(Ω)→L1(Ω)+L∞(Ω) is called the Dunford-Schwartz operator if ||T(f)||1||f||1 (respectively, ||T(f)||∞||f||∞) for all f∈L1(Ω) (respectively, f∈L∞(Ω)). {Tt}

Two sharp inequalities for operators in a Hilbert space
Researches in Mathematics, 2022 In this paper we obtained generalisations of the L. V. Taikov’s and N. Ainulloev’s sharp inequalities, which estimate a norm of function's first-order derivative (L. V. Taikov) and a norm of function's second-order derivative (N.

Connected flow-through chromatography processes as continuous downstream processing of proteins [PDF]
MATEC Web of Conferences, 2019 Continuous manufacturing is expected to increase the productivity of protein drug production. However, it is not easy to build the continuous process especially for downstream processing as many unit operations (chromatography and membrane filtration ...
