Feasibility of distance-regular graphs
Collection: Theses (Ph.D) - Mathematics ดุษฎีนิพนธ์ - คณิตศาสตร์Type: Thesis(Silpakorn University, 12/7/2019)The problem of deciding whether a distance-regular graph with a given intersection array exists is a widely studied topic in distance-regular graphs. In 1989 Brouwer, Cohen and Neumaier have compiled a list of intersection ...
