Connected ring

In mathematics, especially in the field of commutative algebra, a connected ring is a commutative ring A that satisfies one of the following equivalent conditions:A possesses no non-trivial idempotent elements; the spectrum of A with the Zariski topology is a connected space.

Examples and non-examples
Connectedness defines a fairly general class of commutative rings. For example, all local rings and all (meet-)irreducible rings are connected. In particular, all integral domains are connected. Non-examples are given by product rings such as Z × Z; here the element (1, 0) is a non-trivial idempotent. ==Generalizations==
Generalizations
In algebraic geometry, connectedness is generalized to the concept of a connected scheme. ==References==
