We obtain several characterizations of these classes, study their bitopological properties, and investigate their relation with other bitopological sets and mappings.en10.18514/MMN.2009.194info:eu-repo/semantics/openAccess(1,2)*-D(alpha, p) set(1,2)*-D(alpha, s) set(1,2)*-D(c, alpha) set(1,2)*-D(c, s) set(1,2)*-D(c, p) set(1,2)*-D(alpha, p) continuous mapping(1,2)*-D(alpha, s) continuous mapping(1,2)*-D(c, alpha) continuous mapping(1,2)*-D(c, s) continuous mapping(1,2)*-D(c, p) continuous mappingArticle102163171WOS:000273180800006N/A
