Permutation trinomials over : a corrected version
Danyao Wu, Pingzhi Yuan, Cunsheng Ding +1
Permutation polynomials are an interesting subject of mathematics and have applications in other areas of mathematics and engineering. In this paper, we determine all permutation t…
Permutation Polynomials and their Compositional Inverses
Pingzhi Yuan
In this paper, we prove that every PP is an AGW-PP. We also extend the result of Wan and Lidl to other permutation polynomials over finite fields and determine their group structur…
Nonsingular splittings over finite fields
Pingzhi Yuan
We say that and form a \textsl{splitting} of if every nonzero element of has a unique representation of the form with and , while ha…
Some results of strongly primitive tensors
Lihua You, Yafei Chen, Pingzhi Yuan
In this paper, we show that an order dimension 2 tensor is primitive if and only if its majorization matrix is primitive, and then we obtain the characterization of order d…
Sharp upper and lower bounds for the spectral radius of a nonnegative irreducible matrix
Lihua You, Yujie Shu, Pingzhi Yuan
In this paper, we obtain the sharp upper and lower bounds for the spectral radius of a nonnegative irreducible matrix. We also apply these bounds to various matrices associated wit…
New result and some open problems on the primitive degree of nonnegative tensors
Pingzhi Yuan, Zilong He, Lihua You
In this paper, we show that the exponent set of nonnegative primitive tensors with order m(\geq 3) and dimension n is {1,2,\ldots, (n-1)^2+1}; and propose some open problems for fu…
