Let M n ( F ) be the set of all n × n matrices over the field F , where F = R or F = C . We characterize maps on M n ( F ) which are surjective and preserve either the left-star or the right-star order in both directions, but are not necessarily add

Two elements $g$ and $h$ of a permutation group $G$ acting on a set $V$ are said to be intersecting if $g(v) = h(v)$ for some $v \in V$. More generally, a subset ${\cal F}$ of $G$ is an intersecting set if every pair of elements of ${\cal F}$ is inte

Let A be a (0, 1) -matrix such that P A is indecomposable for every permutation matrix P and there are 2 n + 3 positive entries in A . Assume that A is also nonconvertible in a sense that no change of signs of matrix entries, satisfies the condition

We call a function of k variables reducing for a multiplicative semigroup S ⊆ M n ( C ) , if the semigroup is reducible whenever f sends S to zero. For continuous reducing functions on groups of unitary matrices we prove that such a group is reduci
