Invariants of third‐order ordinary differential equations y′′′=f(x,y,y′,y′′) via point transformations
( John Wiley and Sons Ltd , 2016 , Article)A new systematic method to find the relative invariant differentiation operators is developed. We incorporate this new approach with Lie's infinitesimal method to study the general class y′′′ = f(x, y, y′, y′′) under general ...
