We study straight-line drawings of graphs where the vertices are placed in convex position in the plane, i.e., convex drawings. We consider two families of graph classes with nice convex drawings: outer k-planar graphs, where each edge is crossed by at most k other edges; and, outer k-quasi-planar graphs where no k edges can mutually cross. We show that the outer k-planar graphs are (b √ 4k + 1...
The aim of this paper is to characterize in terms of classical (quasi)convexity of extended real-valued functions the set-valued maps which are K-(quasi)convex with respect to a convex cone K. In particular, we recover some known characterizations of K-(quasi)convex vector-valued functions, given by means of the polar cone of K.
The concept of extrasensory perception (ESP) implies that not all perception is dependent upon known physical sensory systems. General ESP is typically sub-divided into three types: (i) telepathy (i.e., alleged direct transference of thoughts), (ii) clairvoyance (i.e., alleged awareness of remote objects or events other than by use of the known sensory channels), and (iii) precognition (i.e., a...
A graph is k-planar (k ≥ 1) if it can be drawn in the plane such that no edge is crossed more than k times. A graph is k-quasi planar (k ≥ 2) if it can be drawn in the plane with no k pairwise crossing edges. The families of k-planar and k-quasi planar graphs have been widely studied in the literature, and several bounds have been proven on their edge density. Nonetheless, only trivial results ...
Let T be a bounded linear operator on complex Hilbert space H. In this paper we introduce two new classes of operators: k−quasi class Q(N ) and Q*(N ). An ∈ L(H) is for fixed real number N ≥ 1 k natural number, if satisfies ∥T^k+1(x)∥^2 ≤ ∥T^k+2(x)∥^2 + ∥T^k(x)∥^2, all x satisfiesN ∥T*T^k(x)∥^2 We study structural spectral properties these operators. Also compare operators with other known
