Temperedness at ramified places for globally generic exceptional groups

OpenAI

For globally generic cuspidal complex automorphic representations of split connected adjoint absolutely simple groups of types G₂, F₄, E₆, E₇ or E₈ over global function fields, every local component is tempered, including arbitrarily ramified places and without a characteristic restriction.

Sources for this record

What was already known

Drinfeld and Lafforgue proved general-linear cases; Lomelí covered split classical and quasi-split unitary groups. The companion OpenAI full-level decomposition gives the unramified result for split adjoint absolutely simple groups, but does not itself address monodromy at ramified places.

AI involvement AI-led

OpenAI is the manuscript author and says its mathematics manuscripts were produced by an internal model. Earlier human results and a companion OpenAI theorem are inputs to this new ramified-place argument.

The repository’s internal-model authorship covers the new ramified-place argument; no individual autonomy record is supplied.

Importance Notable

Extends the generic function-field Ramanujan result to every place for the stated exceptional groups.

Limitations

The ramified-place argument uses a new local coefficient and monodromy comparison plus a companion unramified theorem; no completed check of that comparison is documented.

Technical verification Reported

The source contains a conventional proof but no documented completed check of this ramified-place theorem; Reported is the evidence default.

Human understanding Few

No named human explains the new local criterion; Few is the evidence default.
