On the irregularity of uniform hypergraphs

Let H be an r-uniform hypergraph on n vertices and m edges, and let di be the degree of i∈V(H). Denote by ε(H) the difference between the spectral radius of H and the average degree of H. Also, denote s(H)=∑i∈V(H)|di−rmn|,v(H)=1n∑i∈V(H)dirr−1−rmnrr−1.In this paper, we investigate the irregularity of r-uniform hypergraph H with respect to ε(H), s(H) and v(H), which extend relevant results to uniform hypergraphs.
