Title: Special Solutions of Bi-Riccati Delay-Differential Equations,
Abstract: Delay-differential equations are functional differential equations that
involve shifts and derivatives with respect to a single independent variable.
Some integrability candidates in this class have been identified by various
means. For three of these equations we consider their elliptic and soliton-type
solutions. Using Hirota's bilinear method, we find that two of our equations
possess three-soliton-type solutions.
