*Definition [#a3231f15]
-Let (X, τ, E) be a [[soft topological space]] and let (G, E) be a [[soft set]] over X. The soft closure of (G, E) is the soft set &ref(http://www.eaflux.com/imgtex/imgtex.fcgi?%5bres=100%5d%7b%5c%5b%20%5coverline%7b%28G%2c%20E%29%7d=%5cwidetilde%7b%5ccap%7d%5c%7b%28S%2c%20E%29%5c%2c%7c%5c%2c%20%28S%2c%20E%29%5cmbox%7b%20is%20soft%20closed%20and%20%7d%28G%2c%20E%29%5cwidetilde%7b%5csubseteq%7d%28S%2c%20E%29%5c%7d%20%5c%5d%7d%25.png);.
