  Convenient mixed functions with strongly non-degenerate Newton boundaries
have Milnor fibrations, as the isolatedness of the singularity follows from the
convenience. In this paper, we consider the Milnor fibration for non-convenient
mixed functions. We also study geometric properties such as Thom's $a_f$
condition, the transversality of the nearby fibers and stable boundary property
of the Milnor fibration and their relations.
