The concept of confinement states that in certain systems the constituent particles are bound together by an interaction for which the strength increases with increasing particle separation. One of the consequences of this is that these individual particles cannot be observed directly. The most famous example of confinement is found in particle physics… (More)

A function f is called a graceful labelling of a graph G with q edges if f is an injection from the vertices of G to the set {0, 1, 2,. .. , q} such that, when each edge xy is assigned the label |f(x) − f(y)| , the resulting edge labels are distinct. A graph G is said to be one modulo N graceful (where N is a positive integer) if there is a function φ from… (More)

A graph G is said to be one modulo N graceful (where N is a positive integer) if there is a function φ such a way that (i) φ is 1 − 1 (ii) φ induces a… (More)

The orbital excitations of a series of transition-metal compounds are studied by means of optical spectroscopy. Our aim was to identify signatures of collective orbital excitations by comparison with experimental and theoretical results for predominantly local crystal-field excitations. K 4 Cu 4 OCl 10 , ranging from early to late transition-metal ions,… (More)
