Trivially related lax pairs of the Sawada-Kotera equation %K Sawada-Kotera equation %K Lax pair %K integrability %R %X 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. %U http://bims.iranjournals.ir/article_762_f60c4b68590b1689ee7d3635b080f175.pdf
