A fixedpoint approach for nonlinear discrete boundary value problems
Agarwal, R.P.; O'Regan, D. (Elsevier BV, 19981101) 
A note on equilibria for abstract economies

An essential map approach for multivalued aproper, weakly inward, dkt and weakly closed maps

Boundary value problems for discrete equations
Agarwal, R.P.; O'Regan, D. (Elsevier BV, 19970701)Two existence results are presented for secondorder discrete boundary value problems. The first result is based on the notion of upper and lower solutions and the second result is based on the discrete Gelfand problem.

Discrete systems on infinite intervals
Agarwal, R.P.; O'Regan, D. (Elsevier BV, 19980501)We study superlinear boundary value problems for a discrete system which in particular includes the prototype equation x(k + 1) = f(k,x(k)), equations with finite as well as infinite delays, equations of neutral type, and ...
