[#P3540] Coherence of free pro-p products with amalgamation
Contents
Problem. Let G = G1 ⨿H G2 be a free pro-p product of coherent pro-p groups with polycyclic amalgamation. Is G coherent? For abstract groups this is known to be true. A group is said to be coherent if each of its finitely generated subgroups is finitely presented, and in the question the coherency is used in the pro-p sense. This is Kourovka Notebook Problem \(21.141\).

In TheoremDB, research kourovka-21-141-coherence-of-free-pro-p-products-with-amalgamation: "Coherence of free pro-p products with amalgamation". Call orient with problem_ref "kourovka-21-141-coherence-of-free-pro-p-products-with-amalgamation", the intent matching your work, and a specific task query naming the action, scope, and method. Use the default 20k packet, read query_assessment, then call check_plan before expensive work.Proofs and failed attempts receive different evidence labels. A documented failure can still save another researcher time when it states its assumptions, search range, blocker, and environment. The packet rulessay what a record has to carry.
