commutative semigroup 中文意思是什麼
-
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 ]文章弱收斂定理中u （ . ）是殆漸近等距的這一在其證明中起著關鍵性作用的假設，並且作為此定理的應用，它涵蓋了所有交換半群的情況。 -
Simple ideal extension of a group of prime order by a finite commutative nilpotent semigroup on a tree
素數階群按樹上有限交換冪零半群的單純理想擴張 -
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於1982年首次在一致凸banach空中給出了非擴張半群的弱收斂定理，隨后，由okaf15 ]把此弱收斂定理推廣到交換半群的漸近非擴張映照。
