Turan-type problem for a cycle of length 6 in bipartite Eulerian digraph
نویسنده
چکیده
We prove the following Turán-Type result: If there are more than 9mn/16 edges in a simple and bipartite Eulerian digraph with vertex partition size m and n, then the graph contains a directed cycle of length 4 or 6. By using this result, we improve an upper bound for the diameter of interchange graphs.

A Note on the Number of Edges Guaranteeing a C4 in Eulerian Bipartite Digraphs
Let G be an Eulerian bipartite digraph with vertex partition sizes m,n. We prove the following Turán-type result: If e(G) > 2mn/3 then G contains a directed cycle of length at most 4. The result is sharp. We also show that if e(G) = 2mn/3 and no directed cycle of length at most 4 exists, then G must be biregular. We apply this result in order to obtain an improved upper bound for the diameter o...
متن کاملDisjoint Cycles in Eulerian Digraphs and the Diameter of Interchange Graphs
Let R=(r1, ..., rm) and S=(s1, ..., sn) be nonnegative integral vectors with ; ri=; sj. Let A(R, S) denote the set of all m×n {0, 1}-matrices with row sum vector R and column sum vector S. Suppose A(R, S) ]”. The interchange graph G(R, S) of A(R, S) was defined by Brualdi in 1980. It is the graph with all matrices in A(R, S) as its vertices and two matrices are adjacent provided they differ by ...
متن کاملMonochromatic paths and quasi-monochromatic cycles in edge-coloured bipartite tournaments
We call the digraph D an m-coloured digraph if the arcs of D are coloured with m colours. A directed path (or a directed cycle) is called monochromatic if all of its arcs are coloured alike. A directed cycle is called quasi-monochromatic if with at most one exception all of its arcs are coloured alike. A set N ⊆ V (D) is said to be a kernel by monochromatic paths if it satisfies the following t...
متن کاملEulerian digraphs and Dyck words, a bijection
The main goal of this work is to establish a bijection between Dyck words and a family of Eulerian digraphs. We do so by providing two algorithms implementing such bijection in both directions. The connection between Dyck words and Eulerian digraphs exploits a novel combinatorial structure: a binary matrix, we call Dyck matrix, representing the cycles of an Eulerian digraph. 1. Background, and ...
متن کاملOn the complexity of the Eulerian closed walk with precedence path constraints problem
The Eulerian closed walk problem in a digraph is a well-known polynomial-time solvable problem. In this paper, we show that if we impose the feasible solutions to fulfill some precedence constraints specified by paths of the digraph, then the problem becomes NP-complete. We also present a polynomial-time algorithm to solve this variant of the Eulerian closed walk problem when the paths are arcd...
