Optimal transport on wireless networks

Yong Yu, Bogdan Danila, John A. Marsh +1

We present a study of the application of a variant of a recently introduced heuristic algorithm for the optimization of transport routes on complex networks to the problem of findi…

Martingales, Detrending Data, and the Efficient Market Hypothesis

Joseph L. McCauley, Kevin E. Bassler, Gemunu H. Gunaratne

We discuss martingales, detrending data, and the efficient market hypothesis for stochastic processes x(t) with arbitrary diffusion coefficients D(x,t). Beginning with x-independen…

Nonstationary Increments, Scaling Distributions, and Variable Diffusion Processes in Financial Markets

Kevin E. Bassler, Joseph L. McCauley, Gemunu H. Gunaratne

Arguably the most important problem in quantitative finance is to understand the nature of stochastic processes that underlie market dynamics. One aspect of the solution to this pr…

Linear vs. Nonlinear Diffusion and Martingale Option Pricing

J. L. McCauley, G. H. Gunaratne, K. E. Bassler

First, classes of Markov processes that scale exactly with a Hurst exponent H are derived in closed form. A special case of one class is the Tsallis density, advertised elsewhere a…

Martingale Option Pricing

J. L. McCauley, G. H. Gunaratne, K. E. Bassler

We show that our generalization of the Black-Scholes partial differential equation (pde) for nontrivial diffusion coefficients is equivalent to a Martingale in the risk neutral dis…

Response to Worrying Trends in Econophysics

Joseph L. McCauley

This article is a response to the recent Worrying Trends in Econophysics critique written by four respected theoretical economists. Two of the four have written books and papers th…
