On the roots of the equation $$\zeta (s)=a$$ ζ ( s ) = a

On the roots of the equation $$\zeta (s)=a$$ ζ ( s ) = a Given any complex number $$a$$ a , we prove that there are infinitely many simple roots of the equation $$\zeta (s)=a$$ ζ ( s ) = a with arbitrarily large imaginary part. Besides, we give a heuristic interpretation of a certain regularity of the graph of the curve $$t\mapsto \zeta ({1\over 2}+it)$$ t ↦ ζ ( 1 2 + i t ) . Moreover, we show that the curve $$\mathbb {R}\ni t\mapsto (\zeta ({1\over 2}+it),\zeta '({1\over 2}+it))$$ R ∋ t ↦ ( ζ ( 1 2 + i t ) , ζ ′ ( 1 2 + i t ) ) is not dense in $$\mathbb {C}^2$$ C 2 . http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Abhandlungen aus dem Mathematischen Seminar der Universität Hamburg Springer Journals

Abstract

Given any complex number $$a$$ a , we prove that there are infinitely many simple roots of the equation $$\zeta (s)=a$$ ζ ( s ) = a with arbitrarily large imaginary part. Besides, we give a heuristic interpretation of a certain regularity of the graph of the curve $$t\mapsto \zeta ({1\over 2}+it)$$ t ↦ ζ ( 1 2 + i t ) . Moreover, we show that the curve $$\mathbb {R}\ni t\mapsto (\zeta ({1\over 2}+it),\zeta '({1\over 2}+it))$$ R ∋ t ↦ ( ζ ( 1 2 + i t ) , ζ ′ ( 1 2 + i t ) ) is not dense in $$\mathbb {C}^2$$ C 2 .
