By applying the Leggett-Williams fixed-point theorem, some sufficient conditions guaranteeing the existence of at least two positive solutions are estab-lished under weaker conditions. As an application, an example is given to demonstrate our main results.

在较弱的条件下,利用Leggett-Williams不动点定理,给出了其至少有两个正解存在的充分性条件,并给出了一个例子作为主要结果的应用。

Fixed-point theorem

• abstract: In mathematics, a fixed-point theorem is a result saying that a function F will have at least one fixed point (a point x for which F(x)=x), under some conditions on F that can be stated in general terms. Results of this kind are amongst the most generally useful in mathematics.
