Query: Time and band limiting for matrix valued functions: an integral and a
  commuting differential operator   The problem of recovering a signal of finite duration from a piece of its
Fourier transform was solved at Bell Labs in the $1960$'s, by exploiting a
"miracle": a certain naturally appearing integral operator commutes with an
explicit differential one. Here we show that this same miracle holds in a
matrix valued version of the same problem.
