One-parameter homothetic motion in the Minkowski 3-space
(Işık University Press, 2016)A one-parameter homothetic motion in three-dimensional Minkowski space is defined by means of the Hamilton operators. We study some properties of this motion and show that it has only one pole point at every instant t. We ... -
The connected detour monophonic number of a graph
(Işık University Press, 2016)For a connected graph G = (V, E) of order at least two, a chord of a path P is an edge joining two non-adjacent vertices of P. A path P is called a monophonic path if it is a chordless path. A longest x ? y monophonic path ... -
