Some new sets using soft semi $^{#}galpha$-closed sets in soft topological spaces

In this paper, we define some new sets namely soft semi $^#galpha$-border, soft semi $^#galpha$-frontier and soft semi $^#galpha$-exterior which are denoted by $widetilde{s}$semi $^#galpha$-bd(F,A), $widetilde{s}$semi $^#galpha$-fr(F,A) and $widetilde{s}$semi $^#galpha$-ext(F,A), where (F,A) is any soft set of (X,E) and also investigate their basic properties.
