  The Riccati equation method is used to establish some oscillatory criteria
for the second order linear functional - differential equations of multiple
terms with locally integrable coefficients. An interval oscillation criterion
for the second order linear functional - differential equations is proved. We
have obtained a generalization of an oscillation theorem of L. Berezanski and
E. Braverman, a generalization of the well known Fite's oscillation criterion
and a new global solvability criterion for the second order linear functional -
differential equations with advanced and retarded arguments.
