In this paper we present a tree structure for storing points from a normed space whose norm is effectively computable. We then give an algorithm for finding the nearest point from the tree to a given… (More)

Let p(x) be a polynomial of degree n 2 with coe cients in a sub eld K of the complex numbers. For each natural number m 2, let L m (x) be the m m lower triangular matrix whose diagonal entries are… (More)

This paper presents a microstrip-fed planar antenna, which satisfies “band-notch characteristic”. Antenna's dimensions are 24 mm × 20 mm and its simulated impedance bandwidth spreads across more than… (More)

In this paper we demonstrate how a medium called polynomiography, which consists of techniques for visualization of polynomial equations, can be used to animate mathematical concepts, thereby… (More)

Given a region R in a Euclidean space and a distinguished point p ∈ R, the forbidden zone, F(R, p), is the union of all open balls with center in R, having p as a common boundary point. For a… (More)

We exploit the analogy between the well ordering principle for nonempty subsets of N (the set of natural numbers) and the existence of a greatest lower bound for non-empty subsets of [a, b) 1 to… (More)
