• TITLE: Value Distribution of L-Functions with Rational Moving Targets

  AUTHORS: Matthew Cardwell, Zhuan Ye

  KEYWORDS: Value Distribution; Moving Target; L-Function; Selberg Class

  JOURNAL NAME: Advances in Pure Mathematics, Vol.3 No.9, December 24, 2013

  ABSTRACT: We prove some value-distribution results for a class of L-functions with rational moving targets. The class contains Selberg class, as well as the Riemann-zeta function.
