Toward A Celestial Soft Symmetry Algebra in the $N = 8$ Supergravity

Changhyun Ahn, Man Hea Kim

From the classical $S O (N = 8)$ extended superconformal algebra between the lowest $N = 8$ multiplet in two dimensions obtained by Ademollo et al. (1976), we generalize it…

A Supersymmetric $w_{1 + \infty}$ Symmetry, the Extended Supergravity and the Celestial Holography

Changhyun Ahn, Man Hea Kim

We determine the $N = 4$ supersymmetric $W_{1 + \infty}^{2, 2} [λ = \frac{1}{4}]$ algebra which is an extension of $N = 4$ $S O (4)$ superconformal algebra with vanishing central…

A Supersymmetric Extension of $w_{1 + \infty}$ Algebra in the Celestial Holography

Changhyun Ahn, Man Hea Kim

We determine the $N = 1$ supersymmetric topological $W_{\infty}$ algebra by using the $λ$ deformed bosons $(β, γ)$ and fermions $(b, c)$ ghost system. By considering the real b…

The $N = 2, 4$ Supersymmetric Linear $W_{\infty} [λ]$ Algebras for Generic $λ$ Parameter

Changhyun Ahn, Man Hea Kim

The four different kinds of currents are given by the multiple $(β, γ)$ and $(b, c)$ ghost systems with a multiple product of derivatives. We determine their complete algebra where t…

The Small $N = 4$ Superconformal $W_{\infty}$ Algebra

Changhyun Ahn, Matthias R. Gaberdiel, Man Hea Kim

The symmetric orbifold of $T^{4}$ is the CFT dual of string theory on AdS $_{3} \times S^{3} \times T^{4}$ with minimal NS-NS flux. We study its symmetry algebra and…
