ON THE FRECHET DIFFERENTIABILITY OF LUXEMBURG NORM IN THE SEQUENCE SPACES l^{p_n} WITH VARIABLE EXPONENTS [PDF]

open access: yesRomanian Journal of Mathematics and Computer Science, 2014
It is shown that the Luxemburg norm in the sequence space l^{(p_n)} with variable exponents is Frechet - differentiable and a formula expressing the Frechet derivative of this norm at any nonzero x ∈ l^{(p_n)} is given.

Analytic functions with values in a Frechet space [PDF]

open access: yesPacific Journal of Mathematics, 1962
where {Pn} is a sequence of continuous mutually annihilating projections on F whose ranges are all one-dimensional subspaces of F. This repre­ sentation reduces the study of , which are essentially scalar-valued analytic functions. We actually prove the stronger (and more useful) result that if { k.

On some operator equations in the space of analytic functions and related questions; pp. 81–87 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2013
We investigate extended eigenvalues, extended eigenvectors, and cyclicity problems for some convolution operators. By using the Duhamel product technique, we also estimate the norm of the inner derivation operator ΔA.

Polyline simplification has cubic complexity

open access: yesJournal of Computational Geometry, 2021
$\DeclareMathOperator{\poly}{poly}$In the classic polyline simplification problem, given a polygonal curve~$P$ consisting of $n$ vertices and an error threshold $\delta \geq 0$, we want to replace $P$ by a subsequence~$Q$ of minimal size such that the ...

Demicontinuity and hemicontinuity in Fréchet space [PDF]

open access: yesProceedings of the American Mathematical Society, 1973
It is proved that the notions of demicontinuity and hemicontinuity for monotone maps from a Fréchet space into its dual are equivalent, thus generalizing a result of T. Kato.

On Fermat-Torricelli Problem in Frechet Spaces

open access: yesJournal of Nepal Mathematical Society, 2020
We study the Fermat-Torricelli problem (FTP) for Frechet space X, where X is considered as an inverse limit of projective system of Banach spaces. The FTP is defined by using fixed countable collection of continuous seminorms that defines the topology of X as gauges.
