NettetWe prove that every surjective isometry between unit spheres of L∞(Σ,Ω,μ) L ∞ ( Σ, Ω, μ) and a Banach space F F can be linearly and isometrically extended to the whole space, which means that if the unit sphere of a Banach space F F is isometric to the unit sphere of L∞(Σ,Ω,μ) L ∞ ( Σ, Ω, μ), then F F is linearly isometric to L∞(Σ,Ω,μ) L ∞ ( Σ, … NettetWe obtain that if the set sm. S 1 ( E) of all smooth points of the unit sphere S 1 ( E) is dense in S 1 ( E ), then under some condition, every surjective isometry V 0 from S 1 ( E) onto S 1 ( C (Ω)) can be extended to be a real linearly isometric map V of E onto C (Ω). From this result we also obtain some corollaries. NettetPerson as author : Pontier, L. In : Methodology of plant eco-physiology: proceedings of the Montpellier Symposium, p. 77-82, illus.

NettetProof of Theorem A. Since В is linearly isometric to a C*-algebra and every product on a C*-algebra is Arens regular ([26], [33]), it follows that the product of B** (equal to the third Arens transpose of that of B) is w*-continuous in each of its variables. Then, since В has an approximate unit bounded by one, a Nettet1 Answer.
