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 machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
