This paper presents a variety of existence results for nonlinear Urysohn discrete equations on the infinite interval. In particular, we consider y(i) = ~j°°=o f(i, j, y(j)) for i E {0, 1, 2 .... }. Existence is established using fixed-point arguments. (~) 2001 Elsevier Science Ltd. All rights reser
