GRAPH-THEORETIC CHARACTERIZATION OF SOFT GENERALIZED** Ψ- CLOSED SETS IN SOFT TOPOLOGICAL SPACES VIA BIPARTITE STRUCTURES

Abstract

The  concept  of  soft  sets  was  introduced  by  Dmitri  Molodtsov  as  a  mathematical  tool  for handling  uncertainty  and  imprecise  information,  and  has  since  been  widely  applied  to decision-making  problems  involving  vague  or  ambiguous  data.  In  this  paper,  we  introduce  a new  class  of  soft  sets,  namely  soft  generalized**  -closed  sets  (briefly,  -closed  sets  )  and
