DESCRIPTION:Integer flow of 3-edge colorable cubic signed graphsRong LuoWes
 t Virginia UniversityAbstract: Bouchet conjectured in 1983 that every flow
 -admissible signed graph admits a nowhere-zero 6-flow which is equivalent 
 to the restriction to cubic signed graphs.   Recently we proved that every
  flow-admissible 3-edge-colorable cubic signed graph admits a nowhere-zero
  10-flow.  This together with the 4-color theorem implies that every flow-
 admissible bridgeless planar signed graph admits a nowhere-zero 10-flow. A
 s a byproduct\, we also show that every flow-admissible hamiltonian signed
  graph admits a nowhere-zero 8-flow. This is joint work with C. Li\, LC Li
 \, C.-Q Zhang\, HL ZhangBio: Rong Luo is a professor at the school of Math
 ematical and Data Science at West Virginia University. His research intere
 sts include graph colorings\, flows and cycle cover.
