2-Local derivations on AW$^*$-algebras of type I

Operator Algebras 2015-07-10 v2

Abstract

It is proved that every 2-local derivation on an AW^*-algebra of type I is a derivation. Also an analog of Gleason theorem for signed measures on projections of homogenous AW^*-algebras except the cases of an AW^*-algebra of type I2_2 and a factor of type Im_m, 2<m<2<m<\infty is proved.
