Reciprocal transformations associated with admitted conservation laws were originally used to derive invariance properties in non-relativistic gasdynamics and applied to obtain reduction to tractable canonical forms. They have subsequently been shown to have diverse physical applications to nonlinear systems. notably in the analytic treatment of Stefan-type moving boundary problem and... https://www.countryscenesaddleryandpetsuppliers.shop/product-category/western-show-saddles/
