摘要
本文通过变分法考虑了一类带有异号源和反作用力的传送带问题,利用Ekeland变分原理和分析技巧获得了此类问题正解的存在性.特别地,当反向作用力的正系统足够小时,该问题存在至少3个非平凡解.
In this study,a class problems of transmission belt with different signal sources and reaction force was considered by using the variational method.Based on the Ekeland's variational principle and analytical techniques,the existence of global positive solution was obtained.In particularly,there are at least three nontrivial solutions to this problem when the positive system of the reverse force is small enough.
