| Kurzfassung auf Englisch: |
| We discuss several aspects of Peano-differentiable functions which are definable in an o-minimal structure expanding a real closed field.
After recalling some already known results about o-minimal structures we develop techniques for the intrinsic study of differentiable functions in these structures.
After this we study (ordinary) differentiable functions definable in an o-minimal structure and their continuiuty properties along curves of different differentiability classes.
Then we generalise (ordinary) differentiability to Peano-differentiability.
We study differentiability of certain Peano-derivatives of definable functions and characterise the sets of non-continuity of these derivatives.
In the end we study extendability of these functions defined on closed sets and give sufficient conditions by which we can extend functions as Peano-differentiable functions. |
