“…For instance, quasi-steady-state non-linear problems are addressed in references [15,16,17,18], estimates for advection-diffusion-reaction equation are discussed in [19], similar approaches for the Stokes problem are presented in [20], and extension to parabolic time-dependent problems is introduced in [21,22,23]. Moreover, the same type of tools for coupled problems have been recently discussed in [24,25,26,27,28].…”
