Equality in Degrees of Compactness: Schauder's Theorem and s-numbers

Asuman Güven Aksoy, Daniel Akech Thiong

We investigate an extension of Schauder's theorem by studying the relationship between various $s$ -numbers of an operator $T$ and its adjoint $T^{*}$ . We have three main results. Fir…

Decomposable Blaschke products of degree $2^{n}$

Asuman Güven Aksoy, Francesca Arici, M. Eugenia Celorrio +1

We study the decomposability of a finite Blaschke product $B$ of degree $2^{n}$ into $n$ degree- $2$ Blaschke products, examining the connections between Blaschke products, the ellipt…

Schauder's Theorem and s-Numbers

Asuman Guven Aksoy, Daniel Akech Thiong

Motivated by the well known theorem of Schauder, we study the relationship between various s-numbers of an operator T and its adjoint T* between Banach spaces.

Ideal of hypercyclic operators that factor through $ℓ^{p}$

Asuman Guven Aksoy, Yunied Puig

We study the injective and surjective hull of operator ideals generated by hypercyclic backward weighted shifts that factor through $ℓ^{p}$ .

Isometric Embeddings of Finite Metric Trees into $(R^{n}, d_{1})$ and $(R^{n}, d_{\infty})$

Asuman Güven Aksoy, Mehmet Kiliç, Sahin Koçak

We investigate isometric embeddings of finite metric trees into $(R^{n}, d_{1})$ and $(R^{n}, d_{\infty})$ . We prove that a finite metric tree can be isometrically em…

Extensions of Bernstein's Lethargy Theorem

Asuman Güven Aksoy

In this paper, we examine the aptly-named "Lethargy Theorem" of Bernstein and survey its recent extensions. We show that one of these extensions shrinks the interval for best appro…
