A question of roots of riemann function

Click For Summary

Discussion Overview

The discussion revolves around the limit of the quotient of the Riemann zeta function evaluated at specific roots, particularly focusing on whether this limit can be expressed as an exponential function of a real constant. The context includes theoretical exploration of the properties of the Riemann zeta function and its roots.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant proposes the limit Lim_{x->c}\frac{\zeta(1-x)}{\zeta(x)} as x approaches a root c of the Riemann function and questions if it equals exp(ik) for any real constant k.
  • Another participant asserts that if c is a trivial root, the limit cannot equal exp(ik) for any k.
  • A different participant challenges the idea that k can be any real constant, suggesting it can only be some real constant.
  • One participant discusses the case where c is a trivial root (0 < Re(c) < 1) and references the functional equation of the zeta function, questioning if the limit can be expressed as exp(ik) with k as some real constant.
  • Another participant clarifies that if 0 < Re(c) < 1, it is a non-trivial root and discusses the implications of the function \chi(1-c) on the modulus of the limit, depending on whether c is on the critical line.

Areas of Agreement / Disagreement

Participants express differing views on the nature of the limit and its relationship to the roots of the Riemann zeta function. There is no consensus on whether the limit can be expressed as exp(ik) for any real constant, and the discussion remains unresolved regarding the implications of trivial versus non-trivial roots.

Contextual Notes

Participants reference the functional equation of the zeta function and the properties of the function \chi, but there are unresolved aspects regarding the conditions under which the limit can be evaluated and the implications of the roots' locations.

let be the quotient:

[tex]Lim_{x->c}\frac{\zeta(1-x)}{\zeta(x)}[/tex]
where x=c is a root of riemann function... then my question is if that limit is equal to exp(ik) with k any real constant...thanks... the limit is wehn x tends to c bieng c a root of riemann constant

If c is a trivial root, the answer is clearly no.

If c is a non-trivial root, if you use the functional equation the answer should be clear.

no, that can't be true, k surely cannot be *any* real constant? it can at best be *some* real constant.
 
let,s suppose c is a trivial root i mean 0<re(c)<1 i have checked with the functional equation the limit [tex]Limx->c\frac{\zeta(1-x)}{zeta(x)}[/tex] my question is if we can express this limit as exp(ik) with k some real constant...

i have checked the functional equation for zeta if we call [tex]\zeta(1-s)=F(s)\zeta(s)[/tex] the only thinkg i have proved is that F^*(a+ib)=F(a-ib) (with * complex conjugate) but i don,t know if it will be true that the coefficient is equal to exp(ik).

if 0<Re(c)<1 it is a NON-trivial root.

[tex]\frac{\zeta(1-s)}{\zeta(s)}=\chi(1-s)[/tex], and I'm sure you know what [tex]\chi[/tex] is despite your continued use of "F".

So it depends on [tex]\chi(1-c)[/tex]. If c is on the critical line, this has modulus 1. If c is off the critical line, this may have modulus 1 as well, or it may not.
