Weak (1,1) Shur multipliers and the Hörmander--Mikhlin--Schur theorem

Yongqiang Tian

Let $S_{m}$ be the Schur multiplier with symbol $m$ . We characterize the boundedness of $S_{m} : S^{1} \to S^{1, \infty}$ by approximation of weighted columns in a common fi…

BPS phases and fortuity in higher spin holography

Seok Kim, Jehyun Lee, Siyul Lee +1

We study the BPS states of $U (N)_{k} \times U (1)_{- k}$ vector Chern-Simons theory on a sphere at weak coupling $λ = \frac{N}{k} ≪ 1$ , dual to an AdS $_{4}$ higher spin gravity. Higher spi…

Brane-fused black hole operators

Robert de Mello Koch, Minkyoo Kim, Seok Kim +2

We construct infinitely many new $\frac{1}{16}$ -BPS cohomologies of the 4d maximal super-Yang-Mills theory and interpret them as a black hole wrapped by dual giant graviton hairs.…

Finite $N$ black hole cohomologies

Jaehyeok Choi, Sunjin Choi, Seok Kim +2

We study new cohomologies for the BPS operators of the $N = 4$ Yang-Mills theory with $S U (3)$ and $S U (4)$ gauge groups, to better understand the black hole microstates. We…
