Abstract
The existence of positive periodic solutions is proved forthe higher order singular differential equation $$x^{(n)} + a_{n-1}\, x^{(n-1)} + \dots + a_{1}\,x' + \frac{a_0(t)}{x } = e(t) $$ and for some generalizations, including a class of differential systems with singular cyclic feedback.File in questo prodotto:
