Abstract
Abstract. In this paper, we study the duals of some finite dimensional pointed Hopf algebras working over an algebraically closed field k of characteristic 0. In particular, we study pointed Hopf algebras with coradical k[Γ] for Γ a finite abelian group, and with associated graded Hopf algebra of the form B(V)#k[Γ] where B(V) is the Nichols algebra of V = ⊕iV χi g ∈ i k[Γ] YD. As a corollary k[Γ] to a general theorem on duals of coradically graded Hopf algebras, we have that the dual of B(V)#k[Γ] is B(W)#k[ˆΓ] where W = ⊕iW gi χi ∈ k[ ˆ Γ] k [ ˆ Γ] YD. This description of the dual is used to explicitly describe the Drinfel’d double of B(V)#k[Γ]. We also show that the dual of a nontrivial lifting A of B(V)#k[Γ] which is not itself a Radford biproduct, is never pointed. For V a quantum linear space of dimension 1 or 2, we describe the duals of some liftings of B(V)#k[Γ]. We conclude with some examples where we determine all the irreducible finite-dimensional representations of a lifting of B(V)#k[Γ] by computing the matrix coalgebras in the coradical of the dual.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
