Two ideals A and B in the commutative ring R are called coprime ( or comaximal ) if A + B = R. This generalizes Bézout's identity: with this definition, two principal ideals ( a ) and ( b ) in the ring of integers Z are coprime if and only if a and b are coprime.

Dirac also predicted a reaction + → +, where an electron and a proton annihilate to give two photons.
Reactions such as + → + ( the two-photon annihilation of an electron-positron pair ) are an example.
The single-photon annihilation of an electron-positron pair, + →, cannot occur in free space because it is impossible to conserve energy and momentum together in this process.
