| 1. | Interpolation of periodic functions by harmonic functions is accomplished by Fourier transform.
|
| 2. | Any harmonic function on a compact connected Riemannian manifold is a constant.
|
| 3. | Instead, they resolve to different chords with the same harmonic functions.
|
| 4. | However, this loses the connection with harmonic functions.
|
| 5. | In several ways, the harmonic functions are real analogues to holomorphic functions.
|
| 6. | The uniform limit of a convergent sequence of harmonic functions is still harmonic.
|
| 7. | Harmonic functions are the classical example to which the strong maximum principle applies.
|
| 8. | Harmonic functions that arise in physics are determined by their Liouville's theorem.
|
| 9. | Also, the sum of any two harmonic functions will yield another harmonic function.
|
| 10. | Also, the sum of any two harmonic functions will yield another harmonic function.
