Speaker : Professor Andreas Schweizer (KAIST, Daejeon, South Korea) Value sharing allowing ramification 2014-08-19 (Tue) 10:30 - 11:30 Seminar Room 617, Institute of Mathematics (NTU Campus) Let $f$ be a meromorphic function. We suggest a generalization of $f$ and its derivative $f$ sharing a nonzero complex value $a$ that does not impose any a priori restrictions on the ramification of $f$. Then we discuss some results around the question whether the famous theorem on entire (resp. meromorphic) functions $f$ that share two (resp. three) values with $f$ still holds for this weaker notion.
