Summary: A Generalization of Boolean Rings
Adil Yaqub
Abstract: A Boolean ring satisfies the identity x2 = x which, of course, implies the identity
x2y - xy2 = 0. With this as motivation, we define a subBoolean ring to be a ring R which satisfies
the condition that x2y-xy2 is nilpotent for certain elements x, y of R.
