Conjecture · version 2

Separate conjecture: all nontrivial zeros are simple

Statement

Every nontrivial zero of ζ(s) has multiplicity one.

Assumptions

  • Classical Riemann zeta function.
  • Every nontrivial zero, at every height.

Scope

A multiplicity assertion, separate from the horizontal-position assertion of RH.

RH by itself allows repeated on-line zeros. Simple off-line zeros would satisfy this conjecture but violate RH.

Related statements

Line membership and multiplicity are distinct questions. A zero can be on the line and repeated.

The simple-and-on-line proportion theorem addresses an intersection, not all-zero simplicity.

Every nontrivial zero ρ\rho of the meromorphic continuation of ζ(s)\zeta(s) has Re⁡(ρ)=12\operatorname{Re}(\rho)=\frac12.

  • Classical Riemann zeta function; nontrivial zeros in 0 < Re(s) < 1.

Scope: Every zero at every height; negative-even trivial zeros and the pole at 1 are excluded.

Lamzouri gives a human-authored proof inspired by the Claude result. Appendix A reports AxiomProver (Axiom Math) autoformalization; this is a different role from discovering the original bound.
