利用全局反函数定理和Galerkin方法,考虑了一类半线性波动方程组广义解的存在性,在非线性项f(t,x,u)满足共振的条件下,得到了方程组解的存在唯一性结果.
This paper discusses existence of generalized solutions to periodic boundary value problems for a class of systems of semilinear equations with the nonlineaxity f(t,x,u) at resonance.The argument presented makes use of the global inverse theorem and Galerkin's method.
