Abstract
Let be a locally compact Hausdorff space. Suppose is a C-algebra with the property that every weak-2-local derivation on is a {\rm(}linear{\rm)} derivation. We prove that every weak-2-local derivation on is a {\rm(}linear{\rm)} derivation. Among the consequences we establish that if is an atomic von Neumann algebra or on a compact C-algebra, then every weak-2-local derivation on is a linear derivation. We further show that, for a general von Neumann algebra , every 2-local derivation on is a linear derivation. We also prove several results representing derivations on and on as inner derivations determined by multipliers.
