Abstract: | Dual transformation that produces a path between inhomogeneous spin chains in a site-dependent potential and inhomogeneous spin chains with nonconstant interactions is established. It implies coupling of equivalent random versions of theoretical models. The duality is observed for a number of spin chains with nearest-neighbour as well as multispin interactions. |
