Existence and multiplicity of positive periodic solutions for second-order functional differential equations with infinite delay
In this article, the existence and multiplicity results of positive periodic solutions are obtained for the second-order functional differential equation with infinite delay $$ u''(t)+b(t)u'(t)+a(t)u(t)=c(t)f(t,u_t),\quad t\in \mathbb{R} $$ where $a, b, c$ are continuous $\omeg...
