交换半群 meaning in Chinese

commutative semigroup

This theorem removed the key supposition that the al most - orbit of the semigroup is " almost asymptotically isometric " in li gang [ 20 ] , and as applications , it embraced all the commutative cases
上述定理去掉了ligang [ 20 ]文章弱收敛定理中u ( . )是殆渐近等距的这一在其证明中起着关键性作用的假设，并且作为此定理的应用，它涵盖了所有交换半群的情况。
In 1982 , a weak convergence theorem for nonexpensive semigroups in uniformly convex banach space was first established by miyadera and kobaysi and it was generalized to that for commutative semigroup of asymptotically nonexpansive mappings by oka [ 15 ] . feathers and dotson [ 16 ] and bose [ 1 ] gave the weak convergence theorem of asymptotically nonexpansive mappings in a uniformly convex banach space with weak continuous duality mapping by using opial ' s lemma [ 17 ]
也正是由miyadera和kobayasi于1982年首次在一致凸banach空中给出了非扩张半群的弱收敛定理，随后，由okaf15 ]把此弱收敛定理推广到交换半群的渐近非扩张映照。
