Primitive digraph - k-point exponent - 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 ...
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 ...
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 ...

Let Jrn,k denote the set of n-dimensional cobordism classes containing a representative Mn admitting a(Z2)k-action with fixed point set of constant codimension r.In this paper special generators of the unoriented cobordism ring MO* are constructed to determine the groups J2k+2k-1-2*,k.年份...
Erdős and Guy [11] posed the following generalization: “What is the least number of convex k-gons determined by any set S of n points in the plane?” The trivial solution for the case k=3 is (n3). For convex 4-gons this question is highly non-trivial, as it is related to ...
