Schür’s Theorems on Commutative Matrices [PDF]
Bulletin of the American Mathematical Society, 1944 Summary: In 1905 \textit{I. Schur} [Zur Theorie der vertauschbaren Matrizen. J. Reine Angew. Math. 130, 66-76 (1905; JFM 36.0140.01)] proved that the maximum number \(N(n)\) of linearly independent commutative matrices of \(n\) rows and columns is given by the formula \(N(n)=[n^2/4]+1=\nu^2+1\) if \(n=2\nu\) and \(=\nu(\nu-1)+1\) if \(n=2\nu-1\).

associative ring
International Journal of Mathematics and Mathematical Sciences, 2004 We consider the following condition (*) on an associative ring
R:(*). There exists a function f from R into R such that f is a group homomorphism of (R,+), f is
injective on R2, and f(xy)=(xy)n(x,y) for some
positive integer n(x,y)>1. Commutativity and Scott J. Beslin, Awad Iskanderdoaj +1 more sourceOptimal measurements for simultaneous quantum estimation of multiple

Colloquium Mathematicum, 1996 In this interesting article, the author accomplishes his aim of establishing the commutativity of certain normed *-algebras (not necessarily complete) ``as a consequence of conditions which are seemingly too weak to imply commutativity''. In this case, the sufficient conditions generally involve assumptions about the normality of the elements of the ...openaire +1 more sourceOn some weak conditions of commutativity in common fixed point theorems
International Journal of Mathematics and Mathematical Sciences, 1988 We generalize common fixed point theorems of Fisher and Sessa in complete metric spaces, using some conditions of weak commutativity between a set-valued mapping and a single-valued mapping. Suitable examples prove that these conditions do not imply each M. Imdad, M. S. Khan, S. Sessadoaj +1 more sourceA commutativity theorem for left s-unital rings
International Journal of Mathematics and Mathematical Sciences, 1990 In this paper we generalize some well-known commutativity theorems for associative rings as follows: Let R be a left s-unital ring. If there exist nonnegative integers m>1, k≥0, and n≥0 such that for any x, y in R, [xky−xnym,x]=0, then R is commutative.Hamza A. S.

, 2006 A new, more general derivation of the spin-statistics and PCT theorems is
presented. It uses the notion of the analytic wave front set of
