Is direct product abelian?

Could you please clarify your question regarding the direct product being abelian? Are you referring to the direct product of groups in abstract algebra? If so, the answer is not always straightforward. The direct product of two abelian groups is indeed abelian, as the operation on the product is defined component-wise and thus preserves the commutative property. However, the direct product of non-abelian groups may or may not be abelian, depending on the specific groups and their operations. Can you provide more context or specific examples to narrow down the scope of your inquiry? Is direct product abelian?

The concept of abelian groups in mathematics is fundamental to understanding the properties of direct products of groups. A direct product of groups is considered abelian if and only if each of the component groups is also abelian. This condition arises due to the inherent structure of abelian groups, where the order of multiplication does not affect the result.

To deduce this property, we can consider the center of a group, denoted Z(G), which comprises all elements that commute with every element of the group. For the direct product of groups G1, G2, ..., Gn, the center Z(G1 × G2 × ... × Gn) can be analyzed to gain insights.

Specifically, the center of the direct product is equal to the direct product of the centers of the individual groups: Z(G1 × G2 × ... × Gn) = Z(G1) × Z(G2) × ... × Z(Gn). This equality holds because an element in the center of the direct product must commute with every element in each of the factor groups.

Now, if each of the factor groups G1, G2, ..., Gn is abelian, then their centers coincide with the groups themselves, i.e., Z(G1) = G1, Z(G2) = G2, and so on. Consequently, the center of the direct product becomes the entire direct product: Z(G1 × G2 × ... × Gn) = G1 × G2 × ... × Gn.
