A solution for negative or cooling perturbations is explicitly exhibited, which shows that the system presents sharp propagating fronts.3303-3306engNONLINEAR DIFFUSION PROCESS IN A BENARD SYSTEM AT THE CRITICAL-POINT FOR THE ONSET OF CONVECTIONArtigo10.1103/PhysRevE.47.3303WOS:A1993LF06700038Acesso abertoWOSA1993LF06700038.pdf1599966126072450
