On the Oseen-type resolvent problem associated with time-periodic flow past a rotating body [PDF]

, 2021
Consider the time-periodic flow of an incompressible viscous fluid past a body performing a rigid motion with non-zero translational and rotational velocity. We introduce a framework of homogeneous Sobolev spaces that renders the resolvent problem of the

Asymptotic behavior of resolvents of equilibrium problems on complete geodesic spaces

Demonstratio Mathematica, 2023
In this article, we discuss equilibrium problems and their resolvents on complete geodesic spaces. In particular, we consider asymptotic behavior and continuity of resolvents with positive parameter in a complete geodesic space whose curvature is bounded

Unique solvability of boundary value problem for functional differential equations with involution

Қарағанды университетінің хабаршысы. Математика сериясы, 2021
In this paper we consider a boundary value problem for systems of Fredholm type integral-differential equations with involutive transformation, containing derivative of the required function on the right-hand side under the integral sign.

Separability of the third-order differential operator given on the whole plane

Қарағанды университетінің хабаршысы. Математика сериясы, 2022
In this paper, in the space L2(R2), we study a third-order differential operator with continuous coefficients in R (-∞ , +∞). Here, these coefficients can be unlimited functions at infinity.

Reduction of dimension as a consequence of norm-resolvent convergence and applications [PDF]

, 2018
International audienceThis paper is devoted to dimensional reductions via the norm resolvent convergence. We derive explicit bounds on the resolvent difference as well as spectral asymptotics.

Mixed Problem for a Homogeneous Wave Equation with a Nonzero Initial Velocity and a Summable Potential [PDF]

Известия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2020
For a mixed problem defined by a wave equation with a summable potential equal-order boundary conditions with a derivative and a zero initial position, the properties of the formal solution by the Fourier method are investigated depending on the ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Entanglement of a chiral scalar on the torus

Journal of High Energy Physics
We compute the entanglement entropy of an interval for a chiral scalar on a circle at an arbitrary temperature. We use the resolvent method, which involves expressing the entropy in terms of the resolvent of a certain operator, and we compute that ...

Study of Second-Order Differential Operators on Graphs with Small Edges

Mathematics
In this work, we investigate a Schrödinger operator defined on a model graph containing small loops, under the assumption that the standard nonresonance condition—typically ensuring the holomorphic dependence of the resolvent for elliptic operators on ...

Iterative Methods for Computing the Resolvent of Composed Operators in Hilbert Spaces

Mathematics, 2019
The resolvent is a fundamental concept in studying various operator splitting algorithms. In this paper, we investigate the problem of computing the resolvent of compositions of operators with bounded linear operators.
