SUMMARY

The discussion focuses on proving that if M is an embedded submanifold of N and P is an embedded submanifold of Q, then the product M×P is an embedded submanifold of N×Q. The participants agree that this can be demonstrated by verifying that M×P satisfies the local k-slice condition or by showing that the product of smooth embeddings from the respective inclusion maps is also a smooth embedding. Both methods are confirmed to be valid approaches for establishing the proof.

PREREQUISITES
  • Understanding of embedded submanifolds
  • Familiarity with the local k-slice condition
  • Knowledge of smooth embeddings
  • Basic concepts of manifold theory
NEXT STEPS
  • Study the local k-slice condition in detail
  • Explore the properties of smooth embeddings in manifold theory
  • Research examples of embedded submanifolds in differential geometry
  • Investigate the implications of product manifolds in topology
USEFUL FOR

Mathematicians, particularly those specializing in differential geometry and topology, as well as students seeking to understand the properties of embedded submanifolds and their products.

I'm trying to come up with a simple proof that if M is an embedded submanifold of N, and P is an embedded submanifold of Q, then M×P is an embedded submanifold of N×Q. I'm thinking this could be easily done using showing that M×P satisfies the local k-slice condition, or that the product of smooth embeddings (from the respective inclusion maps) is also a smooth embedding.

Yes, both the slice-condition as the map-condition work. But what did you try? Where are you stuck?
