VORTEX DYNAMICS 1. Introduction
(x) is the scalar vorticity. Equations (4,5) and (6,7) are the basis of the numerical methods discussed in x4. A vortex is typically deflned by a region in the °uid of concentrated vorticity. A simple model is a point vortex in 2D °ow, which corresponds to a straight vortex fllament of unit circulation. The associated scalar vorticity is a ...

www.math.unm.eduKernel density estimation R: violin plot The violin plot uses the function sm.density() rather than density() for the nonparametric density estimate, and this leads to smoother density estimates. If you want to modify the behavior of the violin plot, you can copy the original code to your own function and change how the
The Borel-Cantelli Lemma and its Applications
www.math.unm.edu2 The Borel-Cantelli lemma and applications Lemma 1 (Borel-Cantelli) Let fE kg1 k=1 be a countable family of measur-able subsets of Rd such that X1 k=1 m(E k) <1 Then limsup k!1 (E k) is measurable and has measure zero. Proof. Given the identity, E= limsup k!1 (E k) = \1 n=1 [1 k= E k Since each E k is a measurable subset of Rd, S 1

First, look for I(t) > I 0 for some t > 0. This condition says that the infective population at some time tis larger than the initial number, and could indicate an epidemic.
