More on the Celestial Soft Symmetry Algebra in the $N = 8$ Supergravity

Changhyun Ahn

We construct the operator product expansions (OPEs) of the $N = 8$ $w_{1 + \infty}$ currents (obtained from the antiholomorphic light transform) with the matter fields in…

Multi-Particle Contributions to the Celestial Algebra in the $N = 8$ Supergravity

Changhyun Ahn

Recently, Calkins and Pate calculated the multi-particle operator product expansions (OPEs) of single-particle celestial operators with two-particle celestial operators in pure Ein…

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…

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

Changhyun Ahn

By using the $K$ -free complex bosons and the $K$ -free complex fermions, we construct the $N = 2$ supersymmetric $W_{\infty}^{K, K}$ algebra which is the matrix generalization o…

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…
