“uniqueness theorem”造句，怎么用uniqueness theorem造句

In this paper we discussed the existence and uniqueness theorems for third-order boundary value problems, using the method of upper and lower solutions.

In this paper we give a criterion of uniqueness of solutions to two-point boundary value problem: moreover, we obtain a class of existence uniqueness theorems of solutions.

In this paper, several existence and uniqueness theorems of solutions are proved for the system of nonlinear random operator equations with stochastic domain by using general random contraction.
