Commuting additive maps on tensor products of matrix algebras / Wong Jian Yong

Let k ⩾ 1 and n1, . . . , nk ⩾ 2 be integers. Let F be a field and letMni be the algebra of ni × ni matrices over F for i = 1, . . . , k. Let ⊗ki=1Mni be the tensor product of Mn1 , . . . ,Mnk . In this dissertation, we obtain a complete structural characterization of additive maps ψ : ⊗k i=1 M...
