“…Indeed, for α < 0 there is no solution to (26) because the standard of health does not hold even if all emissions are reduced to zero (that is, any production activity is stopped). The following three results in this section were proved in Parra-Guevara and Skiba (2006. …”

“…Then we can apply the adjoint method to the linearized equation for perturbations ϕ´ and get (19) The last two terms of the right-hand side of (19) demonstrate the contribution of small perturbations U´, µ´, σ´, δr i to variation δJ(ϕ) of mean concentration J(ϕ) in zone Ω. It should be noted that in contrast to estimates (17) and (18), the last term in (19) already contains the solution ϕ(r, t) of non-perturbed problem ( This inverse problem may have many solutions or none, depending on the initial distribution of pollutant ϕ 0 (r) in domain D (Parra-Guevara and Skiba, 2003Skiba, , 2006. So it is an ill-posed problem.…”

“…Introduction. Many real-life applications such as the shape optimization of technological devices [45], the identification of parameters in environmental processes, and flow control problems [15,18,47] lead to optimization problems governed by partial differential equations (PDEs). The complexity of such problems requires special care in order to obtain efficient numerical approximations for the optimization problem.…”
