On some spaces of summable sequences and their duals

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1986
Suppose that S is the space of all summable sequences α with ‖α‖S=supn≥0|∑j=n∞αj| and J the space of all sequences β of bounded variation with ‖β‖J=|β0|+∑j=1∞|βj−βj−1|.

Dual spaces of local Morrey-type spaces [PDF]

open access: yesCzechoslovak Mathematical Journal, 2011
Let \(\omega \) be a weight function on \((0,\infty )\). The local Morrey-type spaces \(LM_{p,\theta ,\omega }\) with the norm \(\| \omega (r)\| f\| _{L_p(B(0,r))}\| _{L_{\theta }(0,\infty )}\) are considered.

Embedding Properties of sets with finite box-counting dimension [PDF]

open access: yes, 2019
In this paper we study the regularity of embeddings of finite--dimensional subsets of Banach spaces into Euclidean spaces. In 1999, Hunt and Kaloshin [Nonlinearity 12 1263-1275] introduced the thickness exponent and proved an embedding theorem for ...

Nuclear Space Facts, Strange and Plain

open access: yesMathematics, 2016
We present a scenic but practical guide through nuclear spaces and their dual spaces, examining useful, unexpected, and often unfamiliar results both for nuclear spaces and their strong and weak duals.

Orthogonality in smooth countably normed spaces

open access: yesJournal of Inequalities and Applications, 2021
We generalize the concepts of normalized duality mapping, J-orthogonality and Birkhoff orthogonality from normed spaces to smooth countably normed spaces.

Generalised Veroneseans [PDF]

open access: yes, 2012
In \cite{ThasHVM}, a characterization of the finite quadric Veronesean $\mathcal{V}_{n}^{2^{n}}$ by means of properties of the set of its tangent spaces is proved. These tangent spaces form a {\em regular generalised dual arc}.

Proper conformal symmetries in SD Einstein spaces [PDF]

open access: yes, 2014
Proper conformal symmetries in self-dual (SD) Einstein spaces are considered. It is shown, that such symmetries are admitted only by the Einstein spaces of the type [N]x[N]. Spaces of the type [N]x[-] are considered in details.

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
We give the second β-, γ-, and f-duals of the sets w0p(Λ), w∞p(Λ ...

On manimax theory in two Hilbert spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1996
In this paper, we investigated the minimax of the bifunction J:H1(Ω)xV2→RmxRn, such that J(v1,v2)=((12a(v1,v1)−L(v1)),v2) where a(.,.) is a finite symmetric bilinear bicontinuous, coercive form on H1(Ω) and L belongs to the dual of H1(Ω).
