Orthogonally additive holomorphic functions on open subsets of C(K)
We introduce, study and characterize orthogonally additive holomorphic functions f:U→ℂ where U is an open subset of C(K). We are led to consider orthogonal additivity at different points of U.
Local Triple Derivations on C*-Algebras†
We prove that every bounded local triple derivation on a unital C*-algebra is a triple derivation. A similar statement is established in the category of unital JB*-algebras.
Geometry of Spaces of Orthogonally Additive Polynomials on C(K)
We study the space of orthogonally additive $n$-homogeneous polynomials on $C(K)$. There are two natural norms on this space. First, there is the usual supremum norm of uniform convergence on the…
Linear disjointness preservers of operator algebras and related structures
We survey some recent studies of linear zero product or orthogonality preservers between C∗/W ∗-algebras, their dual or predual spaces, and holomorphic disjointness preservers of C∗-algebras. Such…
