A representation for the logarithmic derivative $(f'/f)$ of an entire function $f$ of finite order, parametrically in terms of some zeros and critical points of $f ...

In the Introduction to the Derivative video we introduce the notion of the derivative of a function and explain how the derivative captures the instantaneous rate of change of a function. In the ...

We give a logarithmic derivative lemma in several complex variables and its applications to meromorphic solutions of partial differential equations. Journal Information This monthly journal, published ...
