The differentiation operator in the space of uniformly convergent Dirichlet series [PDF]
Mathematische Nachrichten, 2020 Continuity, compactness, the spectrum and ergodic properties of the differentiation operator are investigated, when it acts in the Fréchet space of all Dirichlet series that are uniformly convergent in all half‐planes {s∈C|Res>ε} for each ε>0 .

ON THE BEST APPROXIMATION OF THE DIFFERENTIATION OPERATOR
Ural Mathematical Journal, 2015 In this paper we give a solution of the problem of the best approximation in the uniform norm of the differentiation operator of order k by bounded linear operators in the class of functions with the property that the Fourier transforms of their ...

Hyers-Ulam Stability of Differentiation Operator on Hilbert Spaces of Entire Functions
Journal of Function Spaces, 2014 We investigate the Hyers-Ulam stability of differentiation operator on Hilbert spaces of entire functions. We give a necessary and sufficient condition in order that the operator has the Hyers-Ulam stability and also show that the best constant of Hyers ...

Metrical Boundedness and Compactness of a New Operator between Some Spaces of Analytic Functions
Axioms, 2023 The metrical boundedness and metrical compactness of a new operator from the weighted Bergman-Orlicz spaces to the weighted-type spaces and little weighted-type spaces of analytic functions are characterized.

Қарағанды университетінің хабаршысы. Математика сериясы, 2023 The question of the existence of a solution of linear integro-differential systems of parabolic type limited on the semiaxis in a spatial variable and multiperiodic in time variables was considered. Sufficient conditions of multiperiodic oscillations in

Spectral synthesis for the differentiation operator in the Schwartz space [PDF]
Mathematical Notes, 2017 We consider the spectral synthesis problem for the differentiation operator on the space of infinitely differentiable functions on a finite or infinite interval of the real line and the dual problem of local description of closed submodules in a special ...
