Logarithmic derivatives of theta functions

Israel Journal of Mathematics, 2005
The authors give two new proofs of the identity \[ \sum_{n=0}^\infty \delta(3n+1)x^n= \prod_{n=1}^\infty \frac{(1-x^{3n})^3} {(1-x^n)} \] where \(\delta(n)= d_1(n)- d_2(n)\) is the number of divisors of \(n\) congruent to \(i\bmod 3\). The main tool of the proofs is the theory of theta functions with characteristics: \[ \theta\biggl[ {{\varepsilon ...

On the Growth of the Logarithmic Derivative

Computational Methods and Function Theory, 2001
Let \(f\) be a meromorphic function on \(\mathbb{C}\) with \(f(0)=1\). \textit{A. Gol'dberg} and \textit{V. Grinshtein} [Math. Notes 19, 320-323 (1976; Zbl 0338.30020)] sharpened the lemma of logarithmic derivative in Nevanlinna theory as follows: \[ m\left(r,\frac{f'}{f}\right)\leq \log^+\frac{\rho T(\rho,f)}{r(\rho-r)}+ c, \] where \(\rho>r\), \(c ...
