On the upper chromatic index of a multigraph
نویسندگان
چکیده
We consider the colorings of the edges of a multigraph in such a way that every non-pendant vertex is incident to at least two edges of the same color. The maximum number of colors that can be used in such colorings is the upper chromatic index of a multigraph G, denoted by χ̄(G). We prove that if a multigraph G has n vertices, m edges, p pendant vertices and maximum c disjoint cycles, then χ̄(G) = c + m − n + p.

The chromatic index of multigraphs of order at most 10
The maximum of the maximum degree and the 'odd set quotients' provides a well-known lower bound 4)(G) for the chromatic index of a multigraph G. Plantholt proved that if G is a multigraph of order at most 8, its chromatic index equals qS(G) and that if G is a multigraph of order 10, the chromatic index of G cannot exceed qS(G) + 1. We identify those multigraphs G of order 9 and 10 whose chromat...
متن کاملA Combined Logarithmic Bound on the Chromatic Index of Multigraphs
For any multigraph G of order n, let Φ(G) denote the integer roundup of its fractional chromatic index. We show that the chomatic index χ (G) satisfies χ (G) ≤ Φ(G) + log(min{ n + 1 3 , Φ(G)}). The method used is deterministic (though it extends a famous probabilistic result by Kahn), and different from the re-coloring techniques that are the basis for many of the other known upper bounds on χ ...
متن کاملSome maximum multigraphs and adge/vertex distance colourings
Shannon–Vizing–type problems concerning the upper bound for a distance chromatic index of multigraphs G in terms of the maximum degree ∆(G) are studied. Conjectures generalizing those related to the strong chromatic index are presented. The chromatic d–index and chromatic d–number of paths, cycles, trees and some hypercubes are determined. Among hypercubes, however, the exact order of their gro...
متن کاملOn distance edge colourings of a cyclic multigraph
We shall use the distance chromatic index defined by the present author in early nineties, cf. [5] or [4] of 1993. The edge distance of two edges in a multigraph M is defined to be their distance in the line graph L(M) of M . Given a positive integer d, define the d+-chromatic index of the multigraph M , denoted by q(d)(M), to be equal to the chromatic number χ of the dth power of the line grap...
متن کاملA sublinear bound on the chromatic index of multigraphs
The integer round-up 4(G) of the fractional chromatic index yields the standard lower bound for the chromatic index of a multigraph G. We show that if G has even order n, then the chromatic index exceeds 4(G) by at most max{log,,, n, 1 + n/30}. More generally, we show that for any real b, 2/3 <b < 1, the chromatic index of G exceeds 4(G) by at most max{log,,b n, 1 +n(l b)/lO}. This is used to s...
