We present results from 28 stellar occultations by the large Trans-Neptunian Object (50000) Quaoar registered between 2018 and 2025. By performing a joint analysis of this occultat…
Rational functions that share finite values with their first derivative
Andreas Sauer, Andreas Schweizer
We treat shared value problems for rational functions and their derivative in the plane and on the sphere. We also consider shared values for the pair and $\p…
Meromorphic functions that partially share values with their first derivative
Andreas Sauer, Andreas Schweizer
We consider uniqueness results for meromorphic functions such that for certain values the implication $f(z)=a \Rightarrow…

A. W. Mason, Andreas Schweizer
Let be the ring of elements in an algebraic function field over which are integral outside a fixed place . In contrast to the classical modular group…
