Abstract: In this talk, I discuss physical processes at work in circumstellar disks of Be stars and possible connection to the B[e] phenomenon. On the basis of the viscous decretion disk scenario, I first overview how a disk forms, develops, and dissipates around an isolated Be star. Then, I discuss various effects of a companion on the structure and dynamics of Be disks in binaries, which include the tidal/resonant truncation, the tidal warping and precession, and the Kozai-Lidov oscillations, all of which are important ingredients that cause various system activity. Finally, I briefly comment on the relevance of these processes to supergiant B[e] stars.
