Let B(H) be the C^*-algebra of all bounded linear operators on a complex Hilbert space H. It is proved that an additive surjective map φ on B(H) preserving the star partial order in both directions if and only if one of the following assertions holds. (1) There exist a nonzero complex number a and two unitary operators U and V on H such that φ(X) = a UXV or φ(X) = α UX^* V for all X ∈B(H).

Normal and isometricweighted composition operators on the Fock space. Bull. London. Math. Soc., 2014,46: 847-856), this paper shows that a bounded weighted composition operator onthe Fock space is a Fredholm operator if and only if it is an invertible operator, andif and only if it is a nonzero constant multiple of a unitary operator. The result isvery different from the corresponding results on the Hardy space and the Bergmanspace. 展开更多

Let E be a real uniformly convex and smooth Banach space, and K be a nonempty closed convex subset of E with P as a sunny nonexpansive retraction. Let T1, T2 : K → E be two weakly inward nonself asymptotically nonexpansive mappings with respect to P with a sequence {kn^(i)} [1, ∞) (i = 1, 2), and F := F(T1)∩ F(T2) ≠ 0. An iterative sequence for approximation common fixed points of the two nonself asymptotically nonexpansive mappings is discussed. If E has also a Frechet differentiable norm or its dual E^* has Kadec-Klee property, then weak convergence theorems are obtained. 展开更多

The computations reveal that the rank of the homology of pretzel knots is an invariant of n. The proof is based on a "shortcut" and two lemmas that recursively reduce the computational complexity of Khovanov type homology. 展开更多
