Abstract:

We investigate difference Riccati equations with rational coefficients and delay differential equations with constant coefficients. For difference Riccati equations with some relation among coefficients, we prove that every transcendental meromorphic solution is of order no less than one. We also consider the rational solutions for delay differential equations.

Key words: Difference Riccati equation, Meromorphic solution, Delay differential equation, Rational solution
