≤exPD(v_n).Then exPD(v_k)is called the k- point exponent of D and is denoted by exP_D(k),1≤k≤n.In this paper we define e(n,k):=max{exp_D(k)|D∈PD(n,2)} and E(n,k):= {expD(k)|D∈PD(n,2)},where PD(n,2)is the set of all primitive digraphs of order n...
Typically, the Kohn–Sham equations are solved by minimisation of the total energy functional, using a plane wave basis set for valence electrons and pseudopotentials to obviate the representation of core states. One of the best known and widely used software for performing this type of ...
exponent setLet D=(V, E) be a primitive digraph. The vertex exponent of D at a vertex v ∈V, denoted by expD(v), is the least integer p such that there is a v→u walk of length p for each u ∈ V. Following Brualdi and Liu, we order the vertices of D so that exPD(V1)...

A point set S is said to be k-convex if there exists a k-convex polygon whose vertex set is S. In other words, we are interested in point sets which admit a k-convex polygonization. The introduction of k-convexity of polygons [1] follows the common approach to generalize the notion ...
We consider a variation of the classical Erds-Szekeres problems on the existence and number of convex k-gons and k-holes (empty k-gons) in a set of n points in the plane. Allowing the k-gons to be non-convex, we show bounds and structural results on maximizing and minimizing their ...
