    Isomorphism
In summary, the conversation discusses how to prove that the ring of Cartesian product Z2 X Z2 X Z2...X Z2 is isomorphic to the ring of power set of a set of n elements, P(N), under the operations of addition and multiplication. It is mentioned that both of these rings are Boolean rings and that a ring isomorphism is a one-to-one and onto map preserving both operations. The conversation also mentions using the Stone Representation theorem and suggests considering the case where the multiplication operation is intersection instead of union.

Proving that Z2 X Z2 X Z2... Z2 is a isomorphic (ring isomorphism) to P(N)

Homework Statement


I wish to prove that the ring of Cartesian product Z2 X Z2 X Z2...X Z2 (here we have n products) under addition and multiplication (Z2 is {0,1}) is isomorphic to P(N) where P(N) is the ring of power set of the set of n elements where the multiplication operation is AB=A U B and the addition operation is A+B=(A U B)-(A[itex]\cap[/itex]B)


Homework Equations


Both of these rings are Boolean rings
A ring isomorphism is an operation preserving (both operations) one to one and onto map between the two rings


The Attempt at a Solution


I tried for smaller cases such as Z2 => P(1) and I was able to find an isomorphism through brute force. I want to somehow use the fact that these two rings are Boolean rings to solve this.
While searching for a solution I ran into something called "the Stone Representation theorem" which states that all Boolean Algebras are isomorphic to a field of sets. Is it possible to apply this theorem in this case?

Thank you for the help

Do you know how to prove the isomorphism in the case where the multiplication operation is intersection, rather than union? Think about what happens when each set is replaced with its complement.
 

What is an isomorphism?

An isomorphism is a one-to-one mapping between two mathematical structures that preserves the structure and operations of the structures. In the context of rings, an isomorphism is a bijective function that preserves addition and multiplication operations.

What is the significance of proving that Z2 X Z2 X Z2Z2 is isomorphic to P(N)?

Proving that Z2 X Z2 X Z2Z2 is isomorphic to P(N) shows that the two structures have the same algebraic properties and can be used interchangeably in calculations and proofs. This allows us to better understand the structure of P(N) by relating it to the more familiar structure of Z2 X Z2 X Z2Z2.

How can we prove that Z2 X Z2 X Z2Z2 is isomorphic to P(N)?

We can use the fundamental theorem of ring isomorphisms, which states that if two rings have the same number of elements, they are isomorphic. Since Z2 X Z2 X Z2Z2 and P(N) both have the same cardinality (uncountably infinite), we can conclude that they are isomorphic.

What are the elements of Z2 X Z2 X Z2Z2 and P(N)?

The elements of Z2 X Z2 X Z2Z2 are ordered triples (a, b, c) where a, b, and c are either 0 or 1. The elements of P(N) are subsets of the set of natural numbers (N). For example, the subset {2, 4, 6} would be an element of P(N).

What other structures can Z2 X Z2 X Z2Z2 be isomorphic to?

Z2 X Z2 X Z2Z2 can also be isomorphic to other structures with the same cardinality, such as the group Z2 X Z2 X Z2Z2 or the field R[x] (polynomials with real coefficients). However, it is important to note that isomorphism is a concept that is specific to the operations and structure of the structures being compared, so Z2 X Z2 X Z2Z2 may not be isomorphic to these structures in other contexts.
