The essential norm of bounded diagonal infinite matrices acting on Banach sequence spaces

Demonstratio Mathematica
We calculate the essential norm of bounded diagonal infinite matrices acting on Köthe sequence spaces. As a consequence of our result, we obtain a recent criteria for the compactness of multiplication operator acting on Köthe sequence spaces.

Stable unit balls in Orlicz spaces

, 1990
Let L' (ju) be an Orlicz space and X C LO(p) an ideal such that I(,(f/jjf 1) = 1 for each f e X\{O} . Then the unit ball BX is stable, that is, the midpoint map (I/2:X Bx X BX BX defined by ?1/2(x, Y) = 2 (x + y), is open. In particular, BEj is stable, E

Fubini theorems for Orlicz spaces of Lebesgue-Bochner measurable functions

, 1972
Let (X, V, v) be the volume space formed as the product of the volume spaces (Xi, Vi, v) (i=1, 2). Let (p, q) be a pair of complementary (continuous) Young's functions, let Y, Z, Z1, Z2, W be Banach spaces, let w be a multilinear continuous operator on ...

Extreme Points and Strong U-Points in Musielak–Orlicz Sequence Spaces Equipped with the Orlicz Norm

, 2007
We give some criteria for extreme points and strong U-points in Musielak{ Orlicz sequence spaces equipped with the Orlicz norm. It follows from these results that the notion of the strong U-point is essentially stronger than the notion of the extreme ...

antiSMASH 5.0: updates to the secondary metabolite genome mining pipeline

Nucleic Acids Res., 2019
Secondary metabolites produced by bacteria and fungi are an important source of antimicrobials and other bioactive compounds. In recent years, genome mining has seen broad applications in identifying and characterizing new compounds as well as in ...

Cesàro convergence of martingale difference sequences and the Banach-Saks and Szlenk theorems

, 1988
It is shown that, for 1 2, E(fj, Ej-1) = 0, where Ej is the algebra generated by the simple functions fl,.. ., fj, and hj = gnj, for j = 1,... , k 1. As limn IIE(gn, Ek-1)j1p = 0, we can choose nk > nk-1 with IIE(hk,Sk-1)IIp < 2 , where hk = 9rk We take ...

Traces of Subharmonic Functions to Fractal Sets [PDF]

arXiv, 1999
We study traces of a class of subharmonic functions to Ahlfors regular subsets of $\Co^{n}$. In particular, we establish for the traces a generalized BMO-property and the reverse H\"{o}lder inequality.

Factorable bounded operators and Schwartz spaces

, 1974
A necessary condition for factoring continuous linear maps with domain co or 1l through a class of spaces which include the 4p spaces (in fact, include the Y, spaces) for 2_p Z and J:Z-* Y such that S=JT.
