Bank-Laine functions with real zeros
J. K. Langley
Every real Bank-Laine function of finite order, whose zeros are all real but neither bounded above nor bounded below, either has an explicit representation in terms of trigonometri…

Non-real zeros of derivatives of real meromorphic functions
J. K. Langley
The main result of the paper determines all real meromorphic functions of finite order in the plane for which the first derivative has finitely many zeros, while the function itsel…
