A Charged and Neutral Spin- $4$ Currents in the Grassmannian-like Coset Model

Changhyun Ahn, Minsu Kang

By calculating the second order pole in the operator product expansion (OPE) of the charged spin- $3$ current with the neutral spin- $3$ current in the Grassmannian-like coset model,…

The Structure of the $N = 4$ Supersymmetric Linear $W_{\infty} [λ]$ Algebra

Changhyun Ahn

For the vanishing deformation parameter $λ$ , the full structure of the (anti)commutator relations in the $N = 4$ supersymmetric linear $W_{\infty} [λ = 0]$ algebra is obtained fo…

The $N = 2$ Supersymmetric $w_{1 + \infty}$ Symmetry in the Two-Dimensional SYK Models

Changhyun Ahn

We identify the rank $(q_{sy k} + 1)$ of the interaction of the two-dimensional $N = (2, 2)$ SYK model with the deformation parameter $λ$ in the Bergshoeff, de Wit and Vasiliev(in…

Toward A Supersymmetric $w_{1 + \infty}$ Symmetry in the Celestial Conformal Field Theory

Changhyun Ahn

The $w_{1 + \infty}$ symmetry algebra appears in the Einstein--Yang--Mills theory, proposed recently by Strominger. In this paper, we derive the supersymmetric $w_{1 + \infty}$ symmetr…

M2-branes wrapped on a topological disk

Minwoo Suh

Employing the method applied to M5-branes recently by Bah, Bonetti, Minasian and Nardoni, we study M2-branes on a disk with non-trivial holonomies at the boundary. In four-dimensio…

Worldsheet Free Fields, Higher Spin Symmetry and Free $N = 4$ Super Yang-Mills

Changhyun Ahn

By using the free field worldsheet realization described by Gaberdiel and Gopakumar recently, we construct the nontrivial lowest generators of the higher spin superalgebra $hs(2,2|…
