On the surjectivity conditions of a linear functional differential operator of the second order

Linear second-order functional differential equations without the Volterra condition are studied. Sufficient conditions for the everywhere solvability of the equation (surjectivity of the corresponding functional differential operator) are obtained in terms of norms of the positive and negative part...
