Invertibility of boundary integral operators of elasticity on surfaces with conic points,

open access: yes, 2012
. The system of boundary integral equations of linear isotropic elasticity, with the double layer potential generated by the preudo-stress operator, is considered on surfaces with a finite number of conic points.

Generalized 2-local isometries of spaces of continuously differentiable functions

open access: yes, 2018
Let C(n)(I) denote the Banach space of n-times continuously differentiable functions on I = [0; 1], equipped with the norm ∥Ƥ∥n = max{ |ƒ (0) | ƒ ’ (0) |, …,;ƒ(n-1)(0) | , ∥ ƒ (n) ∥∞ } (ƒ ∈ C (n) (ΐ) ) where ∥ - ∥∞ is the supremum norm. We call a map T :

Hardy-type inequalities for a class of iterated operators and their application to Morrey-type spaces

open access: yesOpen Mathematics
In this study, we discuss new Hardy-type inequalities for operators involving iteration and provide explicit characterizations of these inequalities. As an application of our results, we consider the problem of the boundedness of the multidimensional ...

Eventual ideal properties of the Riemann-Liouville analytic semigroup

open access: yesConcrete Operators
In this paper, we revisit the Riemann–Liouville analytic semigroup. In particular, we completely characterize the membership in the Schatten class Sr ${\mathcal{S}}^{r}$ on L 2(0, 1), as well as the membership in the class of nuclear operators on L p(0,

Embeddings of Rearrangement Invariant Spaces That Are Not Strictly Singular

open access: yes, 1999
. We give partial answers to the following conjecture: the natural embedding of a rearrangement invariant space E into L1 ([0; 1]) is strictly singular if and only if G does not embed into E continuously, where G is the closure of the simple functions in

Estimates for p-adic multilinear Hardy–Littlewood operators on variable Morrey–Herz spaces

open access: yesOpen Mathematics
We obtain some necessary and sufficient conditions for the boundedness of the p-adic multilinear Hardy–Littlewood operators Hφ,n,m ${\mathcal{H}}_{\varphi ,n,m}$ on the p-adic Morrey–Herz spaces ∏i=1mMK̇ℓ,qi(⋅),ωiαi(⋅),λiQpn $\prod _{i=1}^{m}{M \dot {K}}
