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,

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}}

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.

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

MR3667002 Reviewed Vogt, Dietmar(D-BUW) Hadamard operators on D′(Ω). (English summary) Math. Nachr. 290 (2017), no. 8-9, 1374–1380. 46F10 (46F12 47B38)

open access: yes, 2017
In this paper, the Hadamard operators, i.e. a particular class of continuous linear operators on D′(Ω) whose set of eigenvectors is the class of monomials, are considered on an open set Ω⊂Rd.

A q-Rogers–Ramanujan-based characterization of q-bi-bounded turning functions

open access: yesDemonstratio Mathematica
This study investigates the second Hankel determinant for a specific class of functions associated with the q-Rogers–Ramanujan polynomial. To accomplish this, we introduce a new subclass of q-bounded turning functions related to the q-Rogers–Ramanujan ...
