yields a non-unitary 2D CFT whose chiral algebra matches the one from the standard SCFT/VOA correspondence. : The paper demonstrates that the S2cap S squared " by , published in January 2026

The paper explores a novel correspondence between four-dimensional and two-dimensional physics. Its title is a playful reference to the , which relates 6D theories to 4D theories. Key technical highlights include: Dimensional Reduction : It considers four-dimensional
