The spectral radius of graphs with no odd wheels [PDF]

European journal of combinatorics (Print), 2021
The odd wheel W 2 k + 1 is the graph formed by joining a vertex to a cycle of length 2 k . In this paper, we investigate the largest value of the spectral radius of the adjacency matrix of an n -vertex graph that does not contain W 2 k + 1 . We determine
