In this work we determine the structure of 2-torsion-free rings with involution whose nonzero symmetric elements do not annihilate one another. Founded in 1888, to further mathematical research and ...

THE evolution-theory aims at formulating the way in which the present-day state of things has come about. It is not demonstrable like the law of the conservation of energy; it is a way of looking at ...

Let J be a Jordan ring with involution * in which 2x = 0 implies x = 0 and in which 2J = J. Let the set S of symmetric elements of J be periodic and let N be the Jacobson radical of J. Then N2 = 0 and ...
