Abstract: Observations indicate that core-collapse supernova explosions are axisymmetric and bipolar in nature. A rotating core would easily give such a preferred axis of symmetry; at the same time subsequent differential rotation becomes an energy source from which magnetic fields can be amplified. A rapidly and differentially rotating core can also be unstable to non-axisymmetric instabilities, generating MHD waves that propagate through the accreting mantle. We discuss the possible effects of the rotational instabilities in the core on the mantle and the core itself.
