The 3 - dimensional Schrödinger operator H with homogeneous magnetic field ,
perturbed by a periodic potential V , is studied . It is shown that the number of
gaps in the spectrum of H is finite if the field satisfies the condition of magnetic

There is a conjecture that for a generic periodic potential V the spectrum o ( H ( 2
) ) is a Cantor set ( see ( 12 , 21 ] ) ; this conjecture is partly confirmed by the
results of the papers ( 22–24 ] . We briefly describe the results of the present
paper ...
