On Zeros of Solutions of a Second Order Singular Half-linear Equation

abstract:
In the present paper we consider the equation $$ u''=p(t)|u|^\al|u'|^{1-\al}\sgn u, $$ where $\al\in ]0,1]$, the function $p:]a,b[\to R$ is locally integrable, and $\int_a^b(s-a)^\al(b-s)^\al|p(s)|ds<+\infty$. Sufficient conditions for the existence of a solution having at least two zeros on the segment $[a,b]$ are established.
