Abstract

Solutions of the difference equation w(m ⩲ 2) = f (m, w(m), w(m ⩲ 1)) satisfying w(m1) − w(m2) = w1, w(m3) − w(m4) = w2, mi ∈ ℤ, i = 1, 2, 3, 4, and w1, w2 ∈ ℝ, are differentiated with respect to w1 and w2. In addition, differences of solutions with respect to m1, m2, m3 and m4 are considered.
