On the boundedness of the fractional maximal operator on global Orlicz-Morrey spaces
Қарағанды университетінің хабаршысы. Математика сериясы, 2021 The article deals with the global Orlia-Morrey spaces GMΦ,ϕ,θ(Rn). We find sufficient conditions on pairs of functions (ϕ, η) and (Φ, Ψ), which ensure the boundedness of the fractional maximal operator Mα from GMΦ,ϕ,θ(Rn) in GMΨ,η,θ(Rn).

De la Vallée Poussin problem in the kernel of the convolution operator on the half-plane
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2015 We consider the multipoint de la Vallée Poussin (interpolational) problem in the half-plane $D$, $D=\{z \, :\, \mathop{\mathrm{Re}} z0\}$. Let $\psi(z)\in H(D)$; $\mu_1$, $\mu_2$,~$\ldots \in D$ be the positive zero points of this function and let the ...

Combinatorial solution of the eclectic spin chain
Journal of High Energy Physics, 2022 The one-loop dilatation operator in the holomorphic 3-scalar sector of the dynamical fishnet theory is studied. Due to the non-unitary nature of the underlying field theory this operator, dubbed in [1] the eclectic spin chain Hamiltonian, is non ...

Non-commutative peaking phenomena and a local version of the hyperrigidity conjecture
, 2018 We investigate various notions of peaking behaviour for states on a $\mathrm{C}^*$-algebra, where the peaking occurs within an operator system. We pay particularly close attention to the existence of sequences of elements forming an approximation of the ...

On the Green functions of gravitational radiation theory [PDF]
, 2001 Previous work in the literature has studied gravitational radiation in black-hole collisions at the speed of light. In particular, it had been proved that the perturbative field equations may all be reduced to equations in only two independent variables,

On growth characteristics of operator-valued functions [PDF]
Ufimskii Matematicheskii Zhurnal, 2013 In the work we generalize Liouville theorem and the concept of order and type of entire function to the case of an operator-valued function with values in the space Lec(H1,H) of all linear continuous operators acting from a locally convex space H1 to a locally convex space H with an equicontinuous bornology.
