Z-polynomials and Ring Commutativity
We characterise polynomials f with integer coefficients such that a ring with unity R is necessarily commutative if f(x) is central for all x ∈ R. We also solve the corresponding problem without the assumption that the ring has a unity.
متن کاملA COMMUTATIVITY CONDITION FOR RINGS
In this paper, we use the structure theory to prove an analog to a well-known theorem of Herstein as follows: Let R be a ring with center C such that for all x,y ? R either [x,y]= 0 or x-x [x,y]? C for some non negative integer n= n(x,y) dependingon x and y. Then R is commutative.
متن کاملSimultaneous Triangularizability, near Commutativity and Rota's Theorem
In this paper we consider simultaneously triangularizable collections of compact operators and show that similarities of any finite subcollection can be made arbitrarily close to commuting normal operators. As a consequence, we obtain a variant of a theorem of G.-C. Rota. Also, we give some sufficient conditions for simultaneous triangularization of collections of compact operators. Finally, se...
متن کاملSpace-Time Non-Commutativity near Horizon of a Black Hole
We consider dynamics of a quantum scalar field, minimally coupled to classical gravity, in the near-horizon region of a Schwarzschild black-hole. It is described by a static Klein-Gordon operator which in the near-horizon region reduces to a scale invariant Hamiltonian of the system. This Hamiltonian is not essentially self-adjoint, but it admits a one-parameter family of self-adjoint extension...
