math.AC
Inspired by the notion of K\"onig graphs we introduce graded ideals of
K\"onig type with respect to a monomial order $<$. It is shown that if $I$ is
of K\"onig type, then the Cohen--Macaulay property of $\ini_<(I)$ does not
depend on the characteristic of the base field. This h... | arxiv topic:math.AC |

infinitely many n the map c-->f(c) induces a bijection of P^1(F_{q^n}).
Moreover, each of our functions f(X) i... | arxiv topic:math.NT |
