“…where ψ is a contraction mapping, α ∈ (0, 1), µ ∈ (0, 1 L ), L is the spectral radius of A * A, α n ∈ (0, 1) is a real sequence, and λ > 0. Inspired by the work of [8][9][10], many authors have studied (S p VIP) and (FPP) in diverse directions using different techniques (see, for example, [11][12][13][14][15][16][17][18][19][20]).…”
