Abstract :In this research, we define and study the new topological operator called $\\Gamma$-boundary operator $Bd^{\\Gamma}$ by merging local closure function in ideal topological spaces. We research essential properties of this operator and we specialize $\\Gamma$-boundary of some special sets, such as $\\theta$-open, $\\Im_{\\Gamma}$-perfect and $\\Im_{\\Gamma}$-dense. Moreover, we examine the properties of this operator in the topology which is formed by using local closure function. Furthermore, we compare $\\Gamma$-boundary operator with the boundary operator and the $*$-boundary operator. We also show that under what conditions $\\Gamma$-boundary operator, boundary operator and $*$-boundary operator are coincide.
