Graph Hall algebra cohomology realization conjecture
This entry tracks Graph Hall algebra cohomology realization conjecture.
The realization links combinatorial Hall algebras with topological invariants and yields a new graph invariant related to, but distinct from, the Tutte polynomial.
Latest development
The paper establishes Green-type bialgebra structures, identifies primitive elements, gives presentations, and realizes the undirected-graph Hall algebra cohomologically.
Editorial caveat
The source is a preprint, and the broader conjectural framework is not asserted to be settled beyond the stated realization.
