Number Theory Seminar 主講者: Professor Andreas Schweizer (KAIST, Daejeon, South Korea) 講題: Value sharing allowing ramification 時間: 2014-08-19 (Tue.)  10:30 - 11:30 地點: 數學所 617 研討室 (台大院區) Abstract: 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. || Close window ||
