The symplectic strange duality conjecture, conjectured by Beauville is shown to hold for all curves of genus at least two, by using Abe's proof of the conjecture for generic curves, and the above monodromy result.Some references were added, and some minor changes were madeAlgebraic GeometryRepresentation Theory14H60; 14H70text
