For each odd prime power q, we construct an infinite sequence of rational functions f(X) in F_q(X), which is exceptional, means that for infinitely many n the map c-->f(c) induces a bijection P^1(F_{q^n}). Moreover, our indecomposable, it cannot be written as composition lower-degree F_q(X). In case q not 3, these are first known examples indecomposable exceptional over F_q have non-solvable mo...

An {em Italian dominating function} on a digraph $D$ with vertex set $V(D)$ is defined as a function$fcolon V(D)to {0, 1, 2}$ such that every vertex $vin V(D)$ with $f(v)=0$ has at least two in-neighborsassigned 1 under $f$ or one in-neighbor $w$ with $f(w)=2$. A set ${f_1,f_2,ldots,f_d}$ of distinctItalian dominating functions on $D$ with the property that $sum_{i=1}^d f_i(v)le 2$ for each $vi...
