Then we use the deformation process to get the convexity of the spacetime level sets for a class initial boundary value problem for parabolic PDE, under the assumption that the initial data is subharmonic and its level sets is convexity. This is ajoint work with Chen Chuanqiang (USTC) and P.Salani (Firenze). Affiliation:
