Abstract  

A subspaceY of a Banach spaceX is called a Chebyshev one if for everyxX there exists a unique elementP Y(x) inY of best approximation. In this paper, necessary and sufficient conditions are obtained in order that certain classes of subspacesY of the Hardy spaceH 1=H 1 (|z|<1) be Chebyshev ones, and also the properties of the operatorP Y are studied. These results show that the theory of Chebyshev subspaces inH 1 differs sharply from the corresponding theory inL 1(C) of complex-valued functions defined and integrable on the unit circleC:|z|=1. For example, it is proved that inH 1 there exist sufficiently many Chebyshev subspaces of finite dimension or co-dimension (while inL 1(C) there are no Chebyshev subspaces of finite dimension or co-dimension). Besides, it turned out that the collection of the Chebyshev subspacesY with a linear operatorP Y inH 1 (in contrast toL 1(C)) is exhausted by that minimum which is necessary for any Banach space.

Abstract  

The precipitation of uranyl ion with 2-hydroxy-1-naphthaldehyde /2H–1N=HL/ was studied. The solid complex /orange crystals/ was characterized by IR, UV-Vis spectra. Uranium was determined as U3O8 after calcination of the complex at 850°C /37.78% U experimental, 36.64% U calculated for C22H14O6U, UO2L2/. Using a statistical experimental design, the best conditions for quantitative precipitation were obtained. A gravimetric method for the determination of UO 2 2+ is proposed by weighing the complex after drying at 110°C.

Summary A multivariate Hausdorff operator H = H(µ, c, A) is defined in terms of a s-finite Borel measure µ on Rn, a Borel measurable function c on Rn, and an × n matrix A whose entries are Borel measurable functions on rn and such that A is nonsingular µ-a.e. The operator H*:= H (µ, c | det A -1|, A -1) is the adjoint to H in a well-defined sense. Our goal is to prove sufficient conditions for the boundedness of these operators on the real Hardy space H 1(Rn) and BMO (Rn). Our main tool is proving commuting relations among H, H*, and the Riesz transforms Rj. We also prove commuting relations among H, H*, and the Fourier transform.
