On Varieties Which Are Uniruled by Lines
Using the ♯-minimal model program of uniruled varieties we show that for any pair (X,H) consisting of a reduced and irreducible variety X of dimension k ≥ 3 and a globally generated big line bundle H on X with d := H and n := h(X,H) − 1 such that d < 2(n− k)− 4, then X is uniruled of H-degree one, except if (k, d, n) = (3, 27, 19) and a ♯-minimal model of (X,H) is (P3,OP3(3)). We also show that...
متن کاملCausal Characteristic Impedance of Planar Transmission Lines
We compute power-voltage, power-current, and causal definitions of the characteristic impedance of microstrip and coplanar-waveguide transmission lines on insulating and conducting silicon substrates, and compare to measurement.
متن کاملLines on Non-degenerate Surfaces
On an affine variety X defined by homogeneous polynomials, every line in the tangent cone of X is a subvariety of X. However there are many other germs of analytic varieties which are not of cone type but contain “lines” passing through the origin. In this paper, we give a method to determine the existence and the “number” of such lines on non-degenerate surface singualrities.
متن کاملThe arithmetic of characteristic 2 Kummer surfaces and of elliptic Kummer lines
The purpose of this paper is a description of a model of Kummer surfaces in characteristic 2, together with the associated formulas for the pseudo-group law. Since the classical model has bad reduction, a renormalization of the parameters is required, that can be justified using the theory of algebraic theta functions. The formulas that are obtained are very efficient and may be useful in crypt...
متن کاملParametrization of approximate algebraic surfaces by lines
In this paper we present an algorithm for parametrizing approximate algebraic surfaces by lines. The algorithm is applicable to ε-irreducible algebraic surfaces of degree d having an ε-singularity of multiplicity d − 1, and therefore it generalizes the existing approximate parametrization algorithms. In particular, given a tolerance ε > 0 and an ε-irreducible algebraic surface V of degree d , t...
