One way of expressing the self-duality $A\cong \Hom(A,\mathbb{C})$ Abelian groups is that their character tables are self-transpose (in a suitable ordering). Noncommutative fail to satisfy this property. In paper we extend duality some noncommutative considering when table finite group close being transpose for other group. We find dual each have normal subgroup lattices. show our concept cannot work non-nilpotent and describe $p$-group examples.

Attribution in digital marketing is the task of assigning credit due to each interaction toward a outcome. Such information helps brand decide on strategies for future. In web analytics, attribution goes beyond channels, and can be performed across broad range dimensions (e.g. images displayed website). This requires algorithms operate with large number dimensional elements (hundreds thousands extreme). Additionally, given many possible metrics marketer may interested in, it infeasible...

Abstract One way of expressing the self-duality $A\cong {\rm Hom}(A,\mathbb{C})$ Abelian groups is that their character tables are self-transpose (in a suitable ordering). In this paper we extend duality to some noncommutative considering when table finite group close being transpose for other group. We find dual each have normal subgroup lattices. show our concept cannot work non-nilpotent and describe p -group examples.
