A paper published in Computers and Mathematics with Applications provides extensive information regarding different types of soft equal relations. Researchers introduce new notions which generalize soft M-subsets and soft M-equal relations in a natural way. The newly proposed soft L-equal relation =Lis a concept midway between proposition 3.7 and example 3.9 where it is concluded soft J-equality=J is the weakest soft equal relation, while ≡ (=Mand =F) is the soft equal relation in the strictest sense. Researchers use =Mto emphasize that the soft equal relation in one of the equations precisely means the soft M-equal relations. The results concerning generalized soft distributive laws were also amended with the help of soft L-subsets.
