Abstract

We proved the predictions by Ben-Zvi, Sakellaridis, and Venkatesh that the Plancherel algebra PLX\mathrm{PL}_{X} is commutative and its loop-rotated version PLX,ℏ\mathrm{PL}_{X,\hbar} is flat over k[ℏ]k[\hbar].

Provenance statement

The main body of this paper is generated by generative AI. The proof to commutativity of $\mathrm{PL}_X$ and the proof to flatness of $\mathrm{PL}_{X,\hbar}$ are autonomously generated by a math reasoning agent called Rethlas, enhanced by OSVerify, with base model GPT-6-Astra Max. The output is briefly reviewed by human and believed to be overall correct.
