Extension of operators from weak*-closed sub-spaces of into C(K) spaces
W. Johnson, M. Zippin (1995)
Studia Mathematica
Similarity:
It is proved that every operator from a weak*-closed subspace of into a space C(K) of continuous functions on a compact Hausdorff space K can be extended to an operator from to C(K).
On strong generation of B(ℋ) by two commutative C*-algebras
R. Berntzen, A. Sołtysiak (1997)
Studia Mathematica
Similarity:
The algebra B(ℋ) of all bounded operators on a Hilbert space ℋ is generated in the strong operator topology by a single one-dimensional projection and a family of commuting unitary operators with cardinality not exceeding dim ℋ. This answers Problem 8 posed by W. Żelazko in [6].
