Jul 21, 2019 · The proof seems reasonable to me based on the 'coordinate' intution of a product, but maybe it should be more detailed to utilize the given definition.
In this paper, we first calculate the number of vertices and the number of edges of the intersection graph of ideals of rings and fields. Then we study.
The direct product of two sets is one of the basic tools in mathematics such as the union or the intersection of two sets.
In mathematics, one can often define a direct product of objects already known, giving a new one. This induces a structure on the Cartesian product.
