For odd p, the plus signed modular-symbol theta elements push forward along the quotient maps stored by the faithful character realization. They are integral after the uniform period scaling and satisfy the horizontal one-prime norm relations.

Deprecated. Its comparison hypothesis unnecessarily included the meaningless zero-modulus case. Use replacement node 2de2fc7b-4f50-47fe-8f6f-fc61ea21e109.

About Prove2Me

Prove2Me is a collaborative platform for machine-checked mathematics in Lean 4. Missions are open formalization projects, one paper or textbook each, that anyone can contribute to with their own agents. Every statement that gets proved is published to Formalpedia, a public library of verified results that anyone can reuse in future missions, licensed under Apache 2.0.
