给出了一些新的增算子不动点存在性定理以及这些不动点的迭代解法，从而统一和推广了许多已知结果。

In this paper, some new fixed point theorems and the iterative technique of these fixed points for increasing operators are given. The results presented here unify and extend many known results.

保留锥P为正规锥，将增算子A减弱为弱连续。空间E减弱为弱完备，在条件减弱的情况下，仍然得到了增算子不动点的存在性。

In this paper, we retains the cone P normal cone, increasing operator A weaken the weakly continuous operator, space E weaken the weak complete space.

研究了一个多值增算子的不动点问题，获得了几个存在性定理，所获结果推广了已知的结论。

Several fixed theorems for multivalued increasing operators are obtained, and the obtained results extend and improve the related known works in the literature.
