In a recent systematic study, C.Sandon and F.Zanello offered 30 conjectured identities for partitions.In this lecture, we provide proofs for all 30 conjectures
Bizley studied a generalization of Dyck paths from (0, 0) to (pd, qd) (gcd(p, q) =1), which never go below the line py =qx with step set {(0, 1), (1, 0)}, and e
Let G be a graph with a nonzero Laplacian eigenvalue μ of multiplicity k.A line star set for μ in G is a set Y of k edges of G such that μ is not a Laplacian
Let A be a magic square of even order n.A is a Yang Hui type magic square with t-powered sum if for each e =2, 3, … , t, the sum of the elements of the first n
For a given sequence {zn}n≥0 of positive real numbers, {zn}n≥0 is said to be log-concave (or log-convex) if z2n ≥ zn-1zn+1 (or zn2 ≤ zn-1zn+1) for all n ≥
For any graph G, G together with sufficiently many isolated vertices is the competition graph of some acyclic digraph.The competition number k(G) of a graph G i
Let G be a simple undirected graph with n vertices.A stable set of a graph G is a set of vertices no two of which are adjacent.The cardinality of a maximum stab
