چکیده
|
In this note, we present an equivalent condition for linear preservers of group majorization induced by closed subgroup g of o(rn). moreover, a new concept of majorization is defined on r³ as acu-majorization and this is extended for 3×m matrices. then we characterize all its linear preservers on r³ and m3,m.
