摘要
研究了两类平面多项式映射的迭代,讨论了它们在迭代运算下次数不增的条件.对其中一类映射给出了一个充要条件,对另一类映射给出了一个充分条件.
Two classes of planar polynomial maps satisfying that the arbitrary iterates do not increase their degree are studied. A necessary and sufficient condition and a sufficient condition are respectively given for these two classes.
