“…Problem (1.1), (1.2) is a generalization to time scales of the problem when T is restricted to R on the unit interval in Ma and Thompson [19], and extends the type of time-scale boundary value problem found in Anderson [2], Atici and Guseinov [6], Kaufmann [15], Kaufmann and Raffoul [16], and Sun and Li [21,22]. Other related three-point problems on time scales include Anderson and Avery [4], Anderson et al [5], Peterson et al [20], and a singular problem in DaCunha et al [12]. Some of the work on multipoint time-scale problems includes Anderson [1,3] and Kong and Kong [17], and a recent singular multipoint problem in Bohner and Luo [8].…”
