Regular Point Theorem of Manifolds with Boundaries

Click For Summary
SUMMARY

The discussion centers on the Regular Value Theorem as it applies to manifolds with boundaries, contrasting it with the established theorem for manifolds without boundaries. Participants highlight that the preimage of a regular value in manifolds without boundaries results in an imbedding submanifold, while the extension to manifolds with boundaries remains less explored. Milnor's book, "Topology from the Differentiable Viewpoint," is recommended as a key resource for understanding these concepts in Differential Topology. The theorem is also noted as an application of the Implicit Function Theorem, suggesting that extending it to manifolds with boundaries is a valuable exercise.

PREREQUISITES
  • Understanding of Differential Geometry principles
  • Familiarity with the Regular Value Theorem
  • Knowledge of the Implicit Function Theorem
  • Basic concepts of Manifolds and their boundaries
NEXT STEPS
  • Study the implications of the Regular Value Theorem on manifolds with boundaries

  • Explore advanced applications of the Implicit Function Theorem in differential topology
  • Investigate examples of imbedding submanifolds in both bounded and unbounded manifolds
USEFUL FOR

Mathematicians, particularly those specializing in differential geometry and topology, as well as students seeking to deepen their understanding of manifolds with boundaries.

Dear Folks:
In most textbooks on differential geometry, the regular theorem states for manifolds without boundaries: the preimage of a regular value is a imbedding submanifold. What about the monifolds with boundaries??
Many Thanks!

I passionately recommend Milnor's book, Topology from the Differentiable Viewpoint which covers this and many other topics in Differential Topology.

The regular value theorem is an application of the Implicit Function Theorem. Extending it to a manifold with boundary is a good exercise.
