3D Boson representation of affine Yangian of $\mathfrak{g}\mathfrak{l}(1)$ and 3D cut-and-join operators

We have constructed 3D Bosons. In this paper, we show the 3D Bosonic Fock space, which is isomorphic to the vector space of 3D Young diagrams as graded vector spaces. We use 3D Bosons to represent the generators of the affine Yangian of $\mathfrak{g}\mathfrak{l}(1)$ and define the 3D cut-and-join operators. Then we discuss the 3D Boson representation of $W$-operators in matrix models.
