Matrix product solutions to the reflection equation from three dimensional integrability

Abstract : We formulate a quantized reflection equation in which $q$-boson valued $L$ and $K$ matrices satisfy the reflection equation up to conjugation by a solution to the Isaev-Kulish 3D reflection equation. By forming its n-concatenation along the $q$-boson Fock space followed by suitable reductions, we construct families of solutions to the reflection equation in a matrix product form connected to the 3D integrability. They involve the quantum $R$ matrices of the antisymmetric tensor representations of U$_p$ ($A_{n-1}^{(1)}$) and the spin representations of U$_p$($B_n^{(1)}$), $U_p$($D_n^{(1}$) and U$_p$($D_{(n+1)}^{(2)}$)
