Heuristic Approach to Establish New Operators via Nano Topology

引用

Applied Mathematics 2017年第8期8卷 1186-1194页

作者： Lellis Thivagar Maria antony Priyalatha Sundharambal Perumal rajendran School of Mathematics Madurai Kamaraj University Madurai (Dt) India

This article presents a new kind of class of all after composed set and fore composed set using the arbitrary binary relation based on nano topological space. We express the notion of nano equality, and nano inclusion and nano power set regarding binary relation based on nano topology. Also, we discuss their properties. Finally, the real life application of network topology is studied.

关键词： Nano Topology After Composed Set Nano Equality Nano Inclusion Nano Power Set
