Hamiltonian Reduction and Classical Extended Superconformal Algebras

, 1992
We present a systematic construction of classical extended superconformal algebras from the hamiltonian reduction of a class of affine Lie superalgebras, which include an even subalgebra $sl(2)$.

Fast reconstruction method for compressed sensing model with semi-tensor product

Tongxin xuebao, 2018
To reduce the storage space of random measurement matrix and improve the reconstruction efficiency for compressed sensing (CS),a new sampling approach for CS with semi-tensor product (STP-CS) was proposed.The proposed approach generated a low dimensional

On Symmetric Games With Respect to a Permutation Group

IET Control Theory &Applications, Volume 19, Issue 1, January/December 2025.
This paper studies the problem of identifying symmetric games with respect to a permutation group, and derive a minimal discriminant equation system for identifying such games. Compared with the definition‐based approach, this method significantly reduces the computational complexity.

Classical A_n--W-Geometry

, 1992
This is a detailed development for the $A_n$ case, of our previous article entitled "W-Geometries" to be published in Phys. Lett. It is shown that the $A_n$--W-geometry corresponds to chiral surfaces in $CP^n$.

Covariant $W$ Gravity \& its Moduli Space from Gauge Theory

, 1992
In this paper we study arbitrary $W$ algebras related to embeddings of $sl_2$ in a Lie algebra $g$. We give a simple formula for all $W$ transformations, which will enable us to construct the covariant action for general $W$ gravity.
