Local matrix generalizations of $W$-algebras
@article{Zuo2014LocalMG, title={Local matrix generalizations of \$W\$-algebras}, author={Dafeng Zuo}, journal={arXiv: Mathematical Physics}, year={2014} }
In this paper, we propose local matrix generalizations of the classical $W$-algebras based on the second Hamiltonian structure of the $\mathcal{Z}_m$-valued KP hierarchy, where $\mathcal{Z}_m$ is a maximal commutative subalgebra of $gl(m,\mathbb{C})$.
