Some results on total chromatic number of a graph
(Işık University Press, 2017-08-24)A total coloring of a graph is a proper coloring in which no two adjacent or incident graph elements receive the same color. The total chromatic number of a graph is the smallest positive integer for which the graph admits ... -
Position vector of a developable h-slant ruled surface
(Işık University Press, 2017)In physics and geometry, the determination of position vector of a moving point is an important problem, since the trajectory of that point is a curve or a surface which are important in physics, geometry, and applied ... -
