| Abstract: | In this paper author considered oscillatory and asymptotic behaviour of first order NFDE. Author gave some sufficient conditions. under which first order NFDE is oscillatory, from sufficient conditions, under which a characteristic equation has no realroot. And author also gave some sufficient condi tions, under which there exists a nonoscillatory solution of first order NFDE. These criteria simplified results in[1]. |
