Query: On the controllability of some equations of Sobolev-Galpern type   In this paper we deal with the controllability problem for some Sobolev type
equations. We show that the equations cannot be driven to zero if the control
region is strictly supported within the domain. Nevertheless, we also prove
that it is possible to control the equations using controls which have a moving
support, under some assumptions on its movement.
