Convex Noncommutative Polynomials Have Degree Two or Less
A polynomial p (with real coefficients) in noncommutative variables is matrix convex provided p(tX + (1 − t)Y ) ≤ tp(X) + (1 − t)p(Y ) for all 0 ≤ t ≤ 1 and for all tuples X = (X1, . . . , Xg) and Y = (Y1, . . . , Yg) of symmetric matrices on a common finite dimensional vector space of a sufficiently large dimension (depending upon p). The main result of this paper is that every matrix convex p...
متن کاملOn Ideals Which Have the Weakly Insertion of Factors Property
A one-sided ideal of a ring has the insertion of factors property (or simply, IFP) if implies r for . We say a one-sided ideal of has the weakly IFP if for each , implies , for some non-negative integer . We give some examples of ideals which have the weakly IFP but have not the IFP. Connections between ideals of which have the IFP and related ideals of some ring extensions a...
متن کاملIrreducible compositions of degree two polynomials over finite fields have regular structure
Let q be an odd prime power and D be the set of irreducible polynomials in Fq[x] which can be written as a composition of degree two polynomials. In this paper we prove that D has a natural regular structure by showing that there exists a finite automaton having D as accepted language. Our method is constructive.
متن کاملQuadratic Polynomials Which Have a High Density of Prime Values
The University of Manitoba Sieve Unit is used to find several values of A (> 0) such that the quadratic polynomial x + x + A will have a large asymptotic density of prime values. The Hardy-Littlewood constants which characterize this density are also evaluated.
