## The growth of double Dirichlet series.(Chinese. English summary)Zbl 1212.30006

Summary: The authors first study the relations among the coefficients, exponents, and growth of double Dirichlet series, and obtain a necessary and sufficient condition of $$\theta$$ linear lower order, and further give an estimate of $$\theta$$ linear order of double Dirichlet series in every pair of horizontal straight lines.
