The problem of approximating a finite number of functions simultaneously is considered. For a general class of norms, a characterization of best approximations is given. The result generalizes recent work concerned specifically with the Chebyshev norm. 1993 Academic Press, Inc.

## Abstract Compact metric spaces Ο of such a kind, that πΉ~__f__~ =πΉ(__X__), are characterized, πΉ(__X__) is the Οβfield of BOREL sets and πΉ~__f__~(__X__) is the field generated by all open subset of __X__. Our main result is Theorem 5: If Ο is a compact metric space, then the following conditions a
## Abstract We give an intrinsic characterization of the restrictions of Sobolev $W^{k}\_{p}$ (β^__n__^ ), TriebelβLizorkin $F^{s}\_{pq}$(β^__n__^ ) and Besov $B^{s}\_{pq}$(β^__n__^ ) spaces to regular subsets of β^__n__^ via sharp maximal functions and local approximations. (Β© 2006 WILEYβVCH Verl
Criteria for strict monotonicity, lower local uniform monotonicity, upper local uniform monotonicity and uniform monotonicity of a Musielak Orlicz space endowed with the Amemiya norm and its subspace of order continuous elements are given in the cases of nonatomic and the counting measure space. To
