The fullness conjecture for cyclotomic web functors

From papers

Let k\Bbbk be a field, let \mathpzcWebu\mathpzc{Web}_{\mathbf u} be the cyclotomic web category, let W(Λ)W(\Lambda) be the associated WW-algebra, and let Φ^\widehat\Phi be the functor from \mathpzcWebu\mathpzc{Web}_{\mathbf u} to W(Λ)-modW(\Lambda)\text{-mod}. Let \mathpzcWebu,N\mathpzc{Web}_{\mathbf u,N} be the quotient category defined from the finite-NN affine web category. The fullness conjecture. Suppose that k=C\Bbbk=\mathbb C. The functor

Φ^:\mathpzcWebuW(Λ)-mod\widehat\Phi:\mathpzc{Web}_{\mathbf u}\longrightarrow W(\Lambda)\text{-mod}

is full. Moreover, it induces a fully faithful functor from \mathpzcWebu,N\mathpzc{Web}_{\mathbf u,N} to W(Λ)-modW(\Lambda)\text{-mod}. The statement extends the preceding asymptotic faithfulness theorem to fullness and to the finite-NN quotient; the supplied text gives no resolution status.
