摘要: 用时间映像原理证明在非线性项半正情形下带一维Minkowski平均曲率算子的边值问题正解的存在性和多重性, 并将非线性项从f(0)≥0推广到f(0)<0的情形.

关键词: Minkowski平均曲率算子, 正解, 多解性, 时间映像

Abstract: By using the time mapping principle, we prove the existence and multiplicity of positive solutions for the  boundary value problem with one-dimensional Minkowski mean curvature operator in the semipositive case of nonlinear terms and the nonlinear term is generalized from f(0)≥0 to f(0)<0.

Key words: Minkowski mean curvature operator, positive solution, multiplicity, time map
