On the q-deformed modified Korteweg–de Vries hierarchy
PHYSICS LETTERS A(2000)
摘要
We discuss the q-deformed modified KdV hierarchy by factorizing the Lax operator of the q-deformed KdV (q-KdV) hierarchy into multiplication form which defines a q-deformed Miura transformation. We show that the modified hierarchy flows are invariant under cyclic permutations of the Miura variables and, hence, generates Backlund transformations of the q-KdV hierarchy.
