Most calculations of symmetries of differential equations are done with the classical L.V. Ovsyannikov method [1]. In 1965 K.P. Surovikhin published a paper [2], in which the differential forms were applied for searching symmetries. In the K.P. Surovikhin paper the system of hyperbolic type equations was considered, and the canonization method for finding… CONTINUE READING
