Abstract

Let A be an algebra over a commutative unital ring C. We say that A is zero triple product determined if for every C-module X and every trilinear map {,,}, the following holds: if {x,y,z}=0 whenever xyz=0, then there exists a C-linear operator T:A3X such that x,y,z=T(xyz) for all x,y,zA. If the ordinary triple product in the aforementioned definition is replaced by Jordan triple product, then A is called zero Jordan triple product determined. This paper mainly shows that matrix algebra Mn(B), n3, where B is any commutative unital algebra even different from the above mentioned commutative unital algebra C, is always zero triple product determined, and Mn(F), n3, where F is any field with chF2, is also zero Jordan triple product determined.
