چکیده

We present a family of indecomposable polynomials of non prime-power degree over the finite field of three elements which are permutation polynomials over infinitely many finite extensions of the field. The associated geometric monodromy groups are the simple groups PSL2(3 ), where k≥3 is odd. This realizes one of the few possibilities for such a family which remain following the deep work of Fried, Guralnick and Saxl. Acknowledgements. The first author was supported by NSF grant 9224205 and by a bezoekersbeurs of the Nederlandse organisatie voor wetenschappelijk onderzoek (NWO).

A New Family of Exceptional Polynomials in Characteristic Two

We produce a new family of polynomials f(X) over fields k of characteristic 2 which are exceptional, in the sense that f(X)− f(Y ) has no absolutely irreducible factors in k[X,Y ] except for scalar multiples of X−Y ; when k is finite, this condition is equivalent to saying that the map α 7→ f(α) induces a bijection on an infinite algebraic extension of k. Our polynomials have degree 2e−1(2e − 1...

Random matrix theory, the exceptional Lie groups, and L-functions. Abstract There has recently been interest in relating properties of matrices drawn at random from the classical compact groups to statistical characteristics of number-theoretical L-functions. One example is the relationship conjectured to hold between the value distributions of the characteristic polynomials of such matrices an...

Exceptional planar polynomials

Planar functions are special functions from a finite field to itself that give rise to finite projective planes and other combinatorial objects. We consider polynomials over a finite field K that induce planar functions on infinitely many extensions of K; we call such polynomials exceptional planar. Exceptional planar monomials have been recently classified. In this paper we establish a partial...

SCHUR COVERS and CARLITZ’S CONJECTURE

We use the classification of finite simple groups and covering theory in positive characteristic to solve Carlitz’s conjecture (1966). An exceptional polynomial f over a finite field Fq is a polynomial that is a permutation polynomial on infinitely many finite extensions of Fq. Carlitz’s conjecture says f must be of odd degree (if q is odd). Indeed, excluding characteristic 2 and 3, arithmetic ...

Buckling and vibration analysis of angle -ply symmetric laminated composite plates with fully elastic boundaries

The main focus of this paper is on efficiency analysis of two kinds of approximating functions (characteristic orthogonal polynomials and characteristic beam functions) that have been applied in the Rayleigh-Ritz method to determine the non-dimensional buckling and frequency parameters of an angle ply symmetric laminated composite plate with fully elastic boundaries. It has been observed that o...
