A Curvilinear Cluster Set Uniqueness Theorem for Meromorphic Functions.
A note on an extension of Lindelöf's theorem to meromorphic functions.
A note on the separated maximum modulus points of meromorphic functions
We give an upper estimate of Petrenko's deviation for a meromorphic function of finite lower order in terms of Valiron's defect and the number p(∞,f) of separated maximum modulus points of the function. We also present examples showing that this estimate is sharp.

An algebraic addition-theorem for Weierstrass' elliptic function and nomograms
A dual transformation is discussed, by which a concurrent chart represented by one equation is transformed into an alignment chart or into a tangential contact chart. Using this transformation an alignment chart where three scales coincide and a tangential contact chart consisting of a family of circles, which represent the relation , are constructed. In this case, a form of the addition-theorem for Weierstrass’ function involving no derivative is used.
An entire function sharing one small entire function with its derivative.
Analytic functions in the unit disc sharing values in a sector
We deal with the uniqueness of analytic functions in the unit disc sharing four distinct values and obtain two theorems improving a previous result given by Mao and Liu (2009).
