“…In many ways, continuous dependence of the solution in changes in the differential equations or boundary conditions is as important as continuous dependence upon the initial data or stability. In fact, continuous dependence on the model occupies much recent research, see for example, Celik and Hoang, 38 Ciarletta et al, 39 Franchi et al, 18 Gentile and Straughan, 21 Harfash, 40 Hoang and Thinh, 41 Kalantarova and Ugurlu, 42 Li et al, 43 Liu, 44 Liu and Xiao, 45 Liu et al, 46 Scott, 47 Varsakelis and Papalexandris, 48 and Wang and Su 49 …”
