Trivially Related Lax Pairs Of The Sawada-Kotera Equation
We show that a recently introduced Lax pair of the Sawada-Kotera equation is
not a new one but is trivially related to the known old Lax pair. Using the
so-called trivial compositions of the old Lax pairs with a differentially
constrained arbitrary operators, we give some examples of trivial Lax pairs of
KdV and Sawada-Kotera equations.Comment: To Appear in: The Bulletin of the Iranian Mathematical Society (BIMS
