BMO is the space of bounded mean oscillation, that is

\sup_{B}\frac1{B}  \int_B|u-u_B|<\infty

where u_B=\frac1{B}\int_B u.

VMO is the closure of compact support functions in BMO space.

VMO is the closure of compact support continuous functions in BMO space.

BMO is the space of bounded mean oscillation, that is

\sup_{B}\frac1{B}  \int_B|u-u_B|<\infty

where u_B=\frac1{B}\int_B u.

VMO is the closure of compact support functions in BMO space.

But there are also some other kinds of VMO. So you should be careful.
