The density profile of ring chains interacting with a surface and free to belong in a space of size L perpendicular to the surface is found as a function of the intensity of the polymer-surface interactions and the molecular weight of the chains. We work in the frame of the continuous model, and exact analytic expressions are given by means of integral equations and Laplace transforms. The density profiles of rings for the adsorption and depletion cases are described and compared with those of linear chains of the same molecular weight under similar conditions. The ring polymers which have more compact structures due to the closure of their chains are found to be more affected by the surface. (EN)
