We show that any short exact sequence 0 โ K โ โฆ ร C n โ โฆ ร C m โ 0 of holomorphic vector bundles splits over a pseudoconvex open subset โฆ of a Banach space which has a countable unconditional basis.
Given the set V~ of all vectors with length n and components 0, 1 ..... k -1 from the ring of the integers modulo k, the Hamming distance H(X, Y) between X, Y ~ V~ is defined as the number of components in which X and Y differ, and the j-dimensional rook domain of X ~ V~ is defined as the set of vec
In fact, Vizing's proof implies an O(nm) time algorithm with โฌ ฯฉ 1 colors for the edge-coloring problem. However, Holyer has shown that deciding whether a graph requires โฌ or โฌ ฯฉ 1 colors is NP-complete [10]. For a multigraph G, Shannon showed that ะ(G) ี 3โฌ/2 [16]. A number of parallel algorithms
Certain problems involving the coloring the edges or vertices of infinite graphs are shown to be undecidable. In particular, let G and H be finite 3-connected graphs, or triangles. Then a doubly-periodic infinite graph F is constructed such that the following problem is undecidable: For a coloring o
