Mapping formula for functional calculus, Julia's lemma for operators and applications
The first part is devoted to establish a useful mapping formula for functional calculus associated with p-contractions. In the second part, we give a general Julia's lemma for operators whose spectrum is contained in the closed unit disc. Finally, some applications, which are concerned with the...

| Tartalmi kivonat: | The first part is devoted to establish a useful mapping formula for functional calculus associated with p-contractions. In the second part, we give a general Julia's lemma for operators whose spectrum is contained in the closed unit disc. Finally, some applications, which are concerned with the hyperbolic metric on the Harnack parts of p-contractions, are given. |
