Periodic solutions for p(t)-Lienard equations with a singular nonlinearity of attractive type

Petru Jebelean, Jean Mawhin, Calin Serban

We are concerned with the existence of $T$-periodic solutions to an equation of type $$\left (|u'(t))|^{p(t)-2} u'(t) \right )'+f(u(t))u'(t)+g(u(t))=h(t)\quad \mbox{ in }[0,T]$$ wh…
