In the article titled “Supervariable Approach to the Nilpotent Symmetries for a Toy Model of the Hodge Theory” , two equations (i.e., equations 51 and (52)) have been written incorrectly and there are some typing errors in the mathematical expressions that have been incorporated in the text after equation (50). Thus, we are sending, herewith, the correct version of the text after equation (50) and the next paragraph till equation (52). The rest of the paper is correct and there are no errors. The correct text after equation (50) is given below.

By exploiting the (anti-)co-BRST symmetry transformation (4), it can be checked that the above expressions do match with (49) (which is also equivalent to expressions given in (5) in terms of the auxiliary variable b(t)). From the above equations, it becomes transparent that the nilpotency of (anti-)co-BRST charges is deeply connected with the nilpotency (s(a)d2=0) of (anti-)co-BRST symmetry transformations as well as the nilpotency (θ2=0,θ-2=0) of the translational generators θ and θ- along the Grassmannian directions of this (1,2)-dimensional supermanifold. For instance, if we consider Qd=-isdC˙C-+iλ˙b˙, it is clear that sdQd=i{Qd,Qd}=0 because of sd2=0 and the basic definition of a generator of a given transformation. Furthermore, from the suitable expressions from (48), it is very evident that θ-Qd=0 due to θ-2=0 which, in turn, implies that Qd2=0. Such kind of arguments can be given for the nilpotency of Qad as well. Geometrically, the equation Qd=-i/θ-[F˙dF-d+iΛ˙db˙(t)]θ=0 implies that the co-BRST charge Qd is already equivalent to the translation of a composite supervariable (F˙(d)F-(d)+iΛ˙(d)b˙(t)) along the θ--direction of the supermanifold. Thus, any further translation along θ--direction produces a zero result because of the fermionic (θ-2=0) nature of θ-. Similar explanation for the nilpotency of the suitable expression for Qad can be given in the language of nilpotency (θ2=0) of the translational generator θ along θ-direction.
