The problem when Isbell and Scott topology agree on function spaces plays an important rolein the study of topological structure on function spaces. Liu and Liang[19] obtained a solution to the problem in 1996. For studying the compactness of function spaces, Kou and Luo[13] defined property RW. In this paper we discuss further that for RW-space, the conditions on L such that the Isbell and Scott topologies on function space [X→L] agree.It's proved that the following theorems:(1) Let L be a pointed continuous domain with property m. Then the Isbell and Scott topologies on [X→L] agree for all core compact spaces X if and only if L is a bounded complete dcpo.(2) Let L be a continuous L-domain with the least element O_L. Then the Isbell and Scott topologies on [X→L] agree for all RW-spaces X if and only if L is Lawson compact.
