For p > 0, let B(Bn) and Lp(Bn) respectively denote the p-Bloch and holomorphic p-Lipschitz spaces of the open unit ball Bn in C . It is known that B(Bn) and L1−p(Bn) are equal as sets when p ∈ (0, 1). We prove that these spaces are additionally norm-equivalent, thus extending known results for n = 1 and the polydisk. As an application, we generalize work by Madigan on the disk by investigating...
the roots and rhizomes of tanacetum parthenium (l.) schulz. bip. (asteraceae), have been used in iranian traditional medicine under the name of aqhovan, as digestive and stomachic tonic. composition of the essential oil, which was obtained from the root of t. parthenium collected from karaj, was determined by gas chromatography, combined gc/ms and gc/ir. in total, 20 components (92% of essentia...
This paper characterizes the boundedness and compactness of the generalized composition operator (C φf)(z) = ∫ z 0 f ′(φ(ξ))g(ξ)dξ from Bloch type spaces to QK type spaces.
In this paper we introduce a definition of gradation of continuity ingraded fuzzy topological spaces and study its various characteristic properties.The impact of the grade of continuity of mappings over the N-compactnessgrade is examined. Concept of gradation is also introduced in openness, closed-ness, homeomorphic properties of mappings and T2 separation axiom. Effectof the grades interrelat...
ABSTRACT Background and objectives: Utilization of essential oils instead of chemical preservatives has received significant attention in recent years. The present study aims to evaluate chemical composition and antibacterial and antioxidant properties of essential oils of Zataria multiflora, Artemisia deracunculus and Mentha piperita. Methods: Chemical profile of th...
Let X be a Banach space and T bounded linear operator acting in lp(ℤc,X), 1 ≤ p ∞. The is called locally nuclear if it can represented the form $${(Tx)_k} = \sum\limits_{m \in {\mathbb{Z}^c}} {{b_{km}}} {x_{k - m}},\quad k {\mathbb{Z}^c},$$ where bkm: → are nuclear, $${\left\| \right\|_{{\mathfrak{S}_1}}} \le {\beta _m},\quad k,m $$\left\|\cdot\right\|{_{{\mathfrak{S}_1}}}$$ norm, β ∈ l1(ℤc,ℂ) ...
