Pushable homomorphisms and the pushable chromatic number χp of oriented graphs were introduced by Klostermeyer MacGillivray in 2004. They notably observed that, for any graph G⃗, we have χp(G⃗)≤χo(G⃗)≤2χp(G⃗), where χo(G⃗) denotes G⃗. This stands as first general bounds on χp. parameter was further studied later works. work is dedicated to fulfilling particular degree conditions. For all Δ≥29, prove ...

palestinian women have not only collaborated with men in issues such as social, political and cultural affairs but also in literary fields. they have even been pioneer in some fields. a number of senses of contemporary palestinian poetries have been considered by both genders which include different types of sentimental poetries such as ghazals and love poems. although ghazal has been among the...

This contribution introduces and investigates a modelling approach for love dynamics and inspiration by means of System Dynamics, for Laura’s and Petrarch’s emotions as well as for a modern couple in love. In principle, emotions and inspiration emerge from a source and are fading into a sink. But the controlling parameters for increase and decrease of emotion create a broad variety of emotional...
