Sufficient conditions on the function c ( t ) ensuring that the half-linear second order differential equation ( | u ' | p - 2 u ' ) ' + c ( t ) | u ( t ) | p - 2 u ( t ) = 0 , p > 1 possesses a nontrivial solution having at least two zeros in a given interval are obtained. These conditions extend some recently proved conjugacy criteria for linear equations which correspond to the case p = 2 .
