Zero ring - Wikipedia
The unit group of the zero ring is the trivial group {0}. The element 0 in the zero ring is not a zero divisor. The only ideal in the zero ring is the zero ideal {0}, which is also the unit ideal, equal to the whole ring. This ideal is neither maximal nor prime.

Nov 5, 2024 · Trivial Ring. A ring defined on a singleton set . The ring operations (multiplication and addition) are defined in the only possible way, (1) and. (2) It follows that this is a commutative unit ring, where is the multiplicative identity.
Prove that 1 = 0 at the trivial ring - Mathematics Stack Exchange
Jun 14, 2019 · The problem is to prove that zero = one, and then the 5-tupla [T,+,º,zero,one] is true for the boolean function "ring with one" applied to any ring with the property "xºyºx=x", including the trivial ring.

Apr 17, 2022 · Trivial Ring: Given any abelian group \(R\), we can turn \(R\) into a ring by defining multiplication via \(ab=0\) for all \(a,b\in R\). Trivial rings are commutative rings in which every nonzero element is a zero divisor.
Zero ring - Art of Problem Solving
In the category of rings, the zero ring is a terminal object, through the trivial ring homomorphism. However, it is not an initial object. This can be seen by the fact that ring homomorphisms must preserve the identities.
T is called the trivial ring. Note that in T, 0 = 1.

Oct 16, 2012 · A trivial ring is where 1=0. If so, any r = r×1 = r×0 = 0, so there’s only 1 element: {0}. If every non-zero element of the non-trivial ring R is a unit, we call the ring a division ring. If R is a non-trivial commutative ring, and , then we call the ring an integral domain (or just domain if …
