摘要

The aim of this paper is to correct two mistakes in [Appl. Math. Model. 35 (4) (2011) 1798-1809], which are: one of the properties of fuzzy rough set between two different universes and the definition of the upper approximation with the property for degree fuzzy rough set between two different universes.

For the modified properties and the definition of upper approximation for degree fuzzy rough set between two different universes, we claim that the results obtained are correct and the errors have not further implications.
