Financial economics includes the study of the density of 'excess returns,' having skewness, fat tails, and excess kurtosis. We illustrate it using monthly data on a mutual ...

To fight the stagnation of a dull Sunday afternoon, my friend, Sherlock Holmes decided, instead of resorting to his old bad habits, to go to the movie theatre. Based on what ...

Mathematica Notebook showing why Flush doesn't have the same relative rank when you take out the lowest cards - basically because Flush is the only hand in which the number ...

This article shows how symbolic computing and the mathematical formalism induced by maximizing entropy and minimizing the mean deviation from statistical equilibrium may be ...

We consider a special case of the Euler-Poisson system describing the motion of a rigid body with a fixed point. This is an autonomous sixth-order ODE system with one ...

Geodesy is a science whose focus is the determination of high-accuracy spatial coordinates, primarily latitude, longitude, and height. Geodesy is used, for example, in ...

This paper studies center conditions and bifurcation of limit cycles from the equator for a class of polynomial differential system of order seven. By converting real planar ...

Paper and accompanying talk presented at SCI 2000 (July 2000, Orlando, Florida) Abstract: Systems of algebraic equations with finitely many solutions arise in many areas of ...

By the method of synthetic geometry, we define a seemingly new transformation of a three-dimensional projective space where the corresponding points lie on the rays of the ...
