Stability result for a time dependent potential in a waveguide
We consider the operator $H:= \partial_t -\Delta+V$ in $2$D or $3$D waveguide. With an adapted global Carleman estimate with singular weight functions we give a... -
Identification de paramètres magnétiques à l'intérieur d'un tokamak
We study the inverse Cauchy problem which consists in recovering magnetic data (the flux and its normal derivative) inside a tokamak, more precisely in the area... -
