给出了余卷积、余中心元、余扭元、余拟三角双单子的定义,并在单子T的线性型和T-模范畴的辫子之间及单子T的余扭元和T-模范畴的扭元之间建立了双射.
In this paper coconvolution product, linear form, cocentral elements, cotwist, coquasitriangular bimonad are defined. Then a bijection between linear forms of T and braidings C of T-module categories and a bijection between eotwists for T and twists on T-module categories are given.
