A graph G has a representation modulo r if there exists an injective map f : V (G) → {0, 1, . . . , r − 1} such that vertices u and v are adjacent if and only if f(u) − f(v) is relatively prime to r. The representation number rep(G) is the smallest positive integer r for which G has a representation modulo r. In this paper we study representation numbers of the stars K1,n. We will show that the...

Euclidean distance matrices (EDMs) are central players in many diverse fields including psychometrics, NMR spectroscopy, machine learning and sensor networks. However, they are not often exploited in signal processing. In this thesis, we analyze attributes of EDMs and derive new key properties of them. These analyses allow us to propose algorithms to approximate EDMs and provide analytic bounds...
