Average No Regret Sentinel
Keywords:Fractional calculus ; Null-controllability ; Average no regret sentinel ; Pollution term
In this paper, we consider a wave equation with pollution term that includes a fractional derivative of Riemann- Liouville with missing Newman boundary condition and the operator depending on unknown parameter. First we try to avoid the unknown parameter and to isolate the missing function the results are established by introduce the notion of average no regret sentinel. Second is applied the classical approach of sentinel to identify the pollution.
