G \tilde alpha Closed Sets in Bicech Closure Spaces

In this paper, we introduced the concept of G \tilde alpha-closed and G \tilde alpha-open sets in bi-Cech closure spaces and study some of their properties. Further, the concept of _{g\tilde alpha}C_0 bi-Cech space and _{g\tilde alpha}C_1 bi-Cech spaces are introduced and investigate their basic properties.
