【Abstract】 Some properties of trace map are studied, such as exemple measure-preserving, integrable and reversible. When a map on R3 is a trace map associated with invertible substitution, we prove that the map on R2(topollogical equel to the map on R3) is a measure-preserving map. Via studying the involution matric, we can determine a trace map is a reversibe map with substiution matric, at the same time, we can obtain a involution of this trace map. In the end, we study the relationship to the two involutions of a reversible map.更多还原
