Product and coproduct of group category and module category
群与模范畴中的积和余积
Finally , a necessary and sufficient condition for the twisted Smash coproduct comodule categories to be braided monoidal categories is given .
最后，我们给出了扭曲Smash余积余模范畴成为辫monoidal范畴的一个充要条件。
Precipitation of metals under hydrothermal conditions has the advantage of a compact plant but the disadvantage of producing ammonium sulfate as a coproduct .
金属在湿法加热条件下沉淀有利的是设备密实，不利的是产出了副产品硫酸铵；
We define a coproduct on the vector space which has as basis all finite binary trees by using their spine sequences , and construct a cocommutative graded connected Hopf algebra .
In this paper , we discuss the specific structure of product and coproduct of molecular lattices inform Lx ( called power molecular lattices ) in category CD and get formulas :
