“…In the more recent works [9,21], the authors addressed the stability issue for this last problem for quasilinear terms depending only on the solution from some restriction of the Dirichlet-to-Neumann map associated with (1.3). Similar problems have been investigated for more general class of quasilinear terms depending also on the space variable in the works [5,6,22,31,32] among which the most general one can be found in [6] where the authors addressed the open problem of determining quasilinear terms depending simultaneously on the solutions, the gradient of the solutions and the space variable. Finally, we mention the works [13,17,19,20,24,25,27] devoted to the determination of semilinear terms by using the first order linearization technique of [18] as well as the higher order linearization initiated by [26].…”
