let $g=(v,e)$ be a simple graph. a set $ssubseteq v$ isindependent set of $g$, if no two vertices of $s$ are adjacent.the independence number $alpha(g)$ is the size of a maximumindependent set in the graph. in this paper we study and characterize the independent sets ofthe zero-divisor graph $gamma(r)$ and ideal-based zero-divisor graph $gamma_i(r)$of a commutative ring $r$.
In modern telecommunication sectors, zero touch (Zero-Touch) networks are a novel idea. A combination of quick, context-aware network and service configuration, adaptable new development, dynamic, effective resource allocation required for everyone. An innovative management software, Zero-Touch Networks (ZTNs), were released to address these complicated conditions. The primary objective the zer...
Background and Objectives:Groundwater treatment by nano particles has received increasing interest in recent years. Chromium is a commonly identified contaminant in soils and groundwater. Zero-valent iron, as a natural reduction agent can be used in controlling of contaminated sites. The aim of this research is investigation of hexavalent chromium removal from aqueous solutions by using of iron...
The numerically reconstructed images in digital holography contain two undesirable features. After reconstruction, the zero order diffraction as well as the complex conjugate image will be present in pictures and drastically reduce their qualities. Practical applications of digital holography in the context of characterization and measuring the physical properties of objects require the suppres...

In this paper we give a characterization for all commutative rings with $1$ whose zero-divisor graphs are $C_4$-free.
