摘要
本文给出了Robin边值问题(其中a_(?)≥0,b_(?)≥0,a_0+a_1,b_0+b_1>0,a_0+b_0>0)在主要假设f_x≥-β,f_(?)分别在有界和某种无界情形下,有唯一解的一个充分条件。
The present paper deals with Robin's boundary value problem where a_i≥0, b_i≥0, a_0+a_1>0, b_0+b_1>0, a_0+b_0>0. Two sufficient conditions are given respectively for the existence of a unique solution to this boundary value problem under the main assumptions that f_x≥-βand f_(z~′) is bounded or satisfies some unbounded condition.
