On embeddings of compact manifolds

Click For Summary
SUMMARY

This discussion highlights Terence Tao's blog entry on the embeddings of compact manifolds into Euclidean space, specifically referencing the theorems and proofs by Whitney and Nash. It emphasizes that a triangulated manifold with n vertices can naturally embed in the standard n-simplex in R^n, although this embedding is characterized as high-dimensional and not smooth. The insights shared are particularly useful for those exploring the complexities of manifold embeddings.

PREREQUISITES
  • Understanding of compact manifolds
  • Familiarity with Euclidean space concepts
  • Knowledge of triangulated manifolds
  • Basic grasp of theorems by Whitney and Nash
NEXT STEPS
  • Research the Whitney embedding theorem
  • Explore Nash's embedding theorem in detail
  • Study the properties of triangulated manifolds
  • Investigate smooth embeddings in differential geometry
USEFUL FOR

Mathematicians, geometry researchers, and students studying topology and differential geometry will benefit from this discussion, particularly those interested in the theoretical aspects of manifold embeddings.

I have found the following entry on his blog by Terence Tao about embeddings of compact manifolds into Euclidean space (Whitney, Nash). It contains the theorems and (sketches of) proofs. Since it is rather short some of you might be interested in.

hehe, I used that post a couple of days ago when I was checking an argument I was trying to use :)
Very useful indeed.
 
A triangulated manifold with n vertexes naturally embeds in the standard n- simplex in ##R^n##. But this embedding is high dimensional and not smooth.
