    Kumari, M.; Valaulikar, Y.S. (Applications and Applied Mathematics: An International Journal (AAM). 13(2); 2018; 764-780.)
    In this paper we discuss the existence of a solution of a first order neutral differential equation with piecewise constant argument. We extend the method of Chaplygin's sequence to obtain two sided bounds for the solution. ...
