Line integrals and paths with the same endpoints

Click For Summary
SUMMARY

The discussion centers on proving that the line integral of a 1-form w over two smooth curves c1 and c2, which share the same endpoints in an open, path-connected, simply connected subset U of Rn, is equal. The key condition is that U must be simply connected, meaning every closed curve can be continuously deformed to a point. Participants emphasize the importance of understanding the definitions of "one-form" and "exact differential" to approach the proof effectively.

PREREQUISITES
  • Understanding of 1-forms in differential geometry
  • Knowledge of smooth curves in Rn
  • Familiarity with the concept of simply connected spaces
  • Basic principles of homotopy in topology
NEXT STEPS
  • Study the properties of 1-forms and their integrals in differential geometry
  • Learn about homotopy and its implications for line integrals
  • Explore the concept of exact differentials and their role in calculus
  • Review examples of simply connected spaces and their characteristics
USEFUL FOR

Students and educators in advanced calculus, differential geometry, and topology, particularly those focusing on line integrals and their applications in mathematical analysis.

Homework Statement


Suppose that p and q are points in U, where U is an open, path-connected, simply connected subset of Rn and c1 and c2 are smooth curves in Rn with c1(0)=c2(0)=p, c1(1)=c2(1)=q. Let w be a 1-form on U. Prove that the line integral of w over c1 equals the line integral of w over c2.


Homework Equations


simply connected means every closed curve homotopes to a point



I don't know where to start :(

Reading your textbook or lecture notes would be a good place to begin.

You might start with the definition of "one-form". And do you know what an "exact differential" is? It looks to me like the statement you are trying to prove is NOT true unless there are some other conditions.
