The textbook "Some Results on Induced Subgraphs of Johnson Graphs" offers a comprehensive examination of the induced subgraphs of Johnson graphs, which were first addressed in 2010 by R. Naimi and Jaffrey Shaw. The authors present both necessary and sufficient conditions that allow for the determination of whether a given graph can be classified as an induced subgraph of a Johnson graph. This work introduces new sufficient conditions that facilitate the identification of JIS graphs. Additionally, it classifies all graphs with fewer than 6 nodes or a size of less than 7 into the categories of JIS and non-JIS. The book also includes specific examples of JIS and non-JIS graphs. Another focus is on the investigation of a conjecture proposed by Naimi and Shaw, which states that the graph Deltap is JIS if and only if p is odd. The authors have tackled this conjecture and demonstrated that Deltap is indeed JIS when p is odd.
