On Kronecker products of spin characters of the double covers of the 
symmetric groups, 
to appear in Pacific J. Math. 

Abstract: In this article, restrictions on the constituents of Kronecker 
products of spin characters of the double covers of the symmetric groups are
derived. This is then used to classify homogeneous and irreducible products
of spin characters; as an application of this, certain homogeneous 2-modular
tensor products for the symmetric groups are described.
