In a previous paper, we presented new difference-differential equations, and studied their N-soliton solution, elliptic function solutions, and 1-soliw x ton solution under a nonvanishing boundary condition at the infinity 1 . In this note, we present new special solutions for the above equations wh
## Abstract Using a degreeβtheoretic result of Granas, a homotopy is constructed enabling us to show that if there is an __a priori__ bound on all possible __T__βperiodic solutions of a Volterra equation, then there is a __T__βperiodic solution. The __a priori__ bound is established by means of a L
