We present an exponentially convergent semi-implicit meshless algorithm for the solution of Navier-Stokes equations in complex domains. The algorithm discretizes partial derivatives at scattered points using radial basis functions (RBF) as interpolants. Higher-order polynomials are appended to...

This Handbook explores new and old theoretical, methodological, and empirical insights and perspectives on entropy, complexity, and spatial dynamics. A central and cross-cutting theme of the Handbook is the role of entropy in complex, dynamic spatial socio-economic systems as both a measure of...

The basic objective of this investigation is to explore the impactof a novel gravitational modification, specifically, the$f(\mathcal{G}, \mathbf{T}^2)$ (where $\mathcal{G}:=\mathbf{R}^{2}+R_{\alpha\beta\sigma\varsigma}R^{\alpha\beta\sigma\varsigma}-4R_{\alpha\beta}R^{\alpha\beta}$and...

A systematic literature review is used to explore the relationship between complexity theory and economics. Broad search terms identify an unmanageable large number of hits. A more focused search strategy follows the PRISMA protocol and screens for Economics branded publications, and with key...

We investigate the performance of non-linear return prediction models in the high complexity regime, i.e., when the number of model parameters exceeds the number of observations. We document a "virtue of complexity" in all asset classes that we study (US equities, international equities, bonds,...

We study how a firm’s bond structure affects the pricing of its bonds and its base of bond investors. We define bond complexity as the tangle of contractual terms of all outstanding bonds of a firm, and find that it increases bond yield spreads. Specifically, a 1-standard deviation higher...
