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 $W_{1 + \infty}^{2, 2} [I^» = \frac{1}{4}]$ algebra which is an extension of $N = 4$ $S O (4)$ superconformal algebra with vanishing centra…

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 $I^»$ deformed bosons $(I^^{2}, I^^{3})$ and fermions $(b, c)$ ghost system. By considering the rea…
