Toward A Celestial Soft Symmetry Algebra in the Supergravity
Changhyun Ahn, Man Hea Kim
From the classical extended superconformal algebra between the lowest multiplet in two dimensions obtained by Ademollo et al. (1976), we generalize it…
A Charged and Neutral Spin- 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- current with the neutral spin- current in the Grassmannian-like coset model,…
A Supersymmetric Symmetry, the Extended Supergravity and the Celestial Holography
Changhyun Ahn, Man Hea Kim
We determine the supersymmetric algebra which is an extension of superconformal algebra with vanishing central…
A Supersymmetric Extension of Algebra in the Celestial Holography
Changhyun Ahn, Man Hea Kim
We determine the supersymmetric topological algebra by using the deformed bosons and fermions ghost system. By considering the real b…
The Supersymmetric Linear Algebras for Generic Parameter
Changhyun Ahn, Man Hea Kim
The four different kinds of currents are given by the multiple and ghost systems with a multiple product of derivatives. We determine their complete algebra where t…
N=8 SCFT and M Theory on AdS_4 x RP^7
Changhyun Ahn, Hoil Kim, Bum-Hoon Lee +1
We study M theory on $AdS_4 \times \RP^7$ corresponding to 3 dimensional superconformal field theory which is the strong coupling limit of 3 dimensional super Yang-Mil…
