A Classification of a Certain Class of Completely Primary Finite Rings,We consider the isomorphism problem of a class of completely primary finite rings . such that if . is the Jacobson radical of ., then .. = (0) and .. ≠ (0), in the general case, not necessarily the case in which the maximal Galois subrings lie in the center. We further obtain the number of non-isomorphic classes in some special case of these rings.

s density in the envelope pushes the Strömgren sphere of the star onto the stellar surface. We suggest that in the neutral gas envelope close to the star the conditions are favourable for SiO maser formation. More specifically we propose that the BN object is the source of maser emission observed in
