群G上的一个分次张量范畴称为交叉积张量范畴,如果每个齐次分支至少有一个乘法可逆对象。我们的主要结果是用张量范畴上的凝聚外G作用刻画了交叉积张量范畴、分次么整函子、么半自然变换和辫子。
A graded tensor category over a groupGwill be called a crossed product tensor category if every homogeneous component has at least one multiplicatively invertible object. Our main result is a description of crossed product tensor categories, graded monoidal functors, monoidal natural transformations, and braidings in terms of coherent outerG-actions over tensor categories.
