The Chevalley basis Khovanskii basis conjecture

Let \X=\G/\X=\G/\P be a homogeneous space with a dominant weight ϖ\varpi yielding a projective embedding \X\bP(Vϖ)\X\hookrightarrow\bP(V_\varpi), and let \bs\bs be a reduced expression for \wP\wP. A Chevalley basis for VϖV_\varpi is the weight basis obtained from actions of monomials in Chevalley generators. The Chevalley basis Khovanskii basis conjecture. There exists a reduced expression \bs\bs such that the coordinates corresponding to any Chevalley basis for VϖV_\varpi form a Khovanskii basis for \C[\X]\C[\X], and \X\X admits a toric degeneration whose normalization is the toric variety associated to \cP\X,ϖ,\bs\cP_{\X,\varpi,\bs}. The conjecture extends the minuscule construction to arbitrary homogeneous spaces and embeddings; the authors note that the suitable choice of reduced expression and weight basis can affect whether the coordinate valuations generate the valuation semigroup.
