  Topological Integer Additive Set-Valued Graphs: A Review

  By N. K. Sudev, K. P. Chithra, K. A. Germina

  Abstract: AbstractLet denote a set of non-negative integers and be the collection of all non-empty subsets of . An integer additive set-labeling (IASL) of a graph is an injective set-valued function where induced function is defined by , where is the sumset of and . A set-labeling is said to be a topological set-labeling if is a topology on the ground set and a set-labeling is said to be a topogenic …

  A Study on the Sparing Number of the Corona of Certain Graphs

  By K. P. Chithra, K. A. Germina, N. K. Sudev

  Abstract: Let be the set of all non-negative integers and be its the power set. An integer additive set-indexer (IASI) is defined as an injective function such that the induced function defined by is also injective, where is the sum set of and . If , then is said to be a -uniform integer additive set-indexer. An integer additive set-indexer is said to be a weak integer additive set-indexer if . …
