A Kinetic Perspective on k - ϵ Turbulence Model and Corresponding Entropy Production

open access: yesEntropy, 2016
In this paper, we present an alternative derivation of the entropy production in turbulent flows, based on a formal analogy with the kinetic theory of rarefied gas.

Axisymmetric flow of ideal fluid moving in a narrow domain: a study of the axisymmetric hydrostatic Euler equations

open access: yes, 2015
In this article we will introduce a new model to describe the leading order behavior of an ideal and axisymmetric fluid moving in a very narrow domain.

On the Physics of the Riemann Zeros [PDF]

open access: yes, 2010
We discuss a formal derivation of an integral expression for the Li coefficients associated with the Riemann xi-function which, in particular, indicates that their positivity criterion is obeyed, whereby entailing the criticality of the non-trivial zeros.

Formal derivation of a pattern matching algorithm

open access: yesScience of Computer Programming, 1989
The functional version of the Knuth-Morris-Pratt pattern matching algorithm is formally derived using the Bird's calculus of lists. The derivation process is thoroughly explained, various solving strategies are discussed, the paper is self-contained.

Formal moduli problems and formal derived stacks

open access: yes, 2018
This paper presents a survey on formal moduli problems. It starts with an introduction to pointed formal moduli problems and a sketch of proof of a Theorem (independently proven by Lurie and Pridham) which gives a precise mathematical formulation for Drinfeld's derived deformation theory philosophy, which gives a correspondence between formal moduli ...

Gutzwiller density functional theory: a formal derivation and application to ferromagnetic nickel

open access: yesNew Journal of Physics, 2014
We present a detailed derivation of the Gutzwiller density functional theory (DFT) that covers all conceivable cases of symmetries and Gutzwiller wave functions.

On EPP effects and the properties of Core Functional Categories

open access: yesGlossa, 2020
In this paper I argue that EPP effects are not special to T but reflect more general formal properties of the Core Functional Categories (CFCs) C, T, and v.

A microscopic derivation of the quantum mechanical formal scattering cross section

open access: yes, 2005
We prove that the empirical distribution of crossings of a "detector'' surface by scattered particles converges in appropriate limits to the scattering cross section computed by stationary scattering theory.

Continuum limit of self-driven particles with orientation interaction [PDF]

open access: yes, 2007
We consider the discrete Couzin-Vicsek algorithm (CVA), which describes the interactions of individuals among animal societies such as fish schools.

Formal Derivation of Pointer Algorithms [PDF]

open access: yes, 1991
We show that the well-known unfold/fold transformation strategy also is fruitful for the (formal) derivation of correct pointer algorithms. The key that allows this extension is the algebra of partial maps which allows convenient description and manipulation of pointer structures at the functional level.
