Uniqueness of the solution with certain boundary conditions

Click For Summary
SUMMARY

The uniqueness of solutions in electrodynamics with Dirichlet and Neumann boundary conditions is confirmed under specific circumstances. When dealing with linear equations, the solutions are guaranteed to be unique, provided the boundary conditions are appropriately applied. The discussion emphasizes the importance of understanding the mathematical characteristics of linear equations to establish this uniqueness. Participants are encouraged to explore proofs that leverage these characteristics.

Hey!


Speaking electrodynamics, I can't seem to get mathematically or even physically convinced that the solution with Dirichlet or Neumann boundary conditions is UNIQUE.

Can someone explain it?

Thanks.

What equation are you solving? Sometimes you have uniqueness, sometimes you might not depending on the problem and the boundary conditions.

Are the equations linear? If so, are you aware that the solution has to be unique? See if you can prove this mathematically by making use of the characteristics of linear equations.
