Infinite elements in the universal sets

Click For Summary
SUMMARY

Venn diagrams can represent both finite and infinite sets, as demonstrated in the discussion regarding the sets V = {all odd numbers} and W = {5, 15, 25, 45, 55,...}. The relationship indicates that W is a subset of V, illustrating how Venn diagrams can effectively show connections between infinite elements. While traditionally used for logical arguments, the application of Venn diagrams to non-finite sets raises questions about their utility in counting infinite elements.

PREREQUISITES
  • Understanding of set theory and infinite sets
  • Familiarity with Venn diagrams and their applications
  • Basic knowledge of subsets and their relationships
  • Concept of cardinality in mathematics
NEXT STEPS
  • Research the properties of infinite sets in set theory
  • Explore advanced applications of Venn diagrams in mathematics
  • Study the concept of cardinality and its implications for infinite sets
  • Investigate the historical context of Venn diagrams and their original purpose
USEFUL FOR

Mathematicians, educators, students studying set theory, and anyone interested in the visualization of infinite sets using Venn diagrams.

is it possible to make a venn diagram wherein the elements are infinite elements?

ex. V = { is the set of all odd numbers)
W = { 5, 15, 25, 45, 55,...}

thanks a lot

I have never seen it done.

All sets are infinite? The circles in a Venn diagram can denote finite or infinite sets. The circles show how the sets are related. In this case, it seems that W is a subset of V.

I agree that Venn himself used the diagrams for logical arguments.
But the OP said "the elements are infinite elements". I take that to mean some sort of counting.
Have you seem Venn's diagrams used for counting non-finite sets?
