AGT relations for abelian quiver gauge theories on ALE spaces
Bibliographic record
Abstract
We construct level one dominant representations of the affine Kac-Moody algebra $mathfrak{gl}_k$ on the equivariant cohomology groups of moduli spaces of rank one framed sheaves on the orbifold compactification of the minimal resolution $X_k$ of the $A_{k-1}$ toric singularity $mathbb{C}^2/mathbb{Z}_k$. We show that the direct sum of the fundamental classes of these moduli spaces is a Whittaker vector for $mathfrak{gl}_k$, which proves the AGT correspondence for pure N=2 U(1) gauge theory on Xk. We consider Carlsson-Okounkov type Ext-bundles over products of the moduli spaces and use their Euler classes to define vertex operators. Under the decomposition $mathfrak{gl}_k≃mathfrak{h}oplus$mathfrak{sl}_k$, these vertex operators decompose as products of bosonic exponentials associated to the Heisenberg algebra h and primary fields of $mathfrak{sl}_k$. We use these operators to prove the AGT correspondence for N=2 superconformal abelian quiver gauge theories on $X_k$.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
