%X It is known that for an IP* set  in £¿ and a sequence £¿£¿¡Þ=1 there exists a sum subsystem £¿£¿¡Þ=1 of £¿£¿¡Þ=1 such that (£¿£¿¡Þ=1)¡È(£¿£¿¡Þ=1)£¿. Similar types of results also have been proved for central* sets. In this present work we will extend the results for dense subsemigroups of ((0,¡Þ),
