The Multivariate Theory of Functional Connections: Theory, Proofs, and Application in Partial Differential Equations

open access: yesMathematics, 2020
This article presents a reformulation of the Theory of Functional Connections: a general methodology for functional interpolation that can embed a set of user-specified linear constraints. The reformulation presented in this paper exploits the underlying

Randall Collins’ micro-sociology, the Southern culture of honor, and the codes of violence pathway: Toward a general theory of violence

open access: yesSocial Sciences and Humanities Open, 2022
One of Randall Collins' principal theoretical projects is the advancement of a general theory of violence. The central framing mechanism driving Collins approach is the concept of confrontational tension/fear, and the various pathways a social actor ...

Mathematical Structure of Loop Quantum Cosmology: Homogeneous Models

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2013
The mathematical structure of homogeneous loop quantum cosmology is analyzed, starting with and taking into account the general classification of homogeneous connections not restricted to be Abelian.

Quantum integrability from non-simply laced quiver gauge theory

open access: yesJournal of High Energy Physics, 2018
We consider the compactifcation of 5d non-simply laced fractional quiver gauge theory constructed in [1]. In contrast to the simply laced quivers, here two Ω-background parameters play different roles, so that we can take two possible Nekrasov ...

Abelian Chern–Simons theory, Stokes’ theorem, and generalized connections

open access: yesJournal of Geometry and Physics, 2012
Generalized connections and their calculus have been developed in the context of quantum gravity. Here we apply them to abelian Chern-Simons theory. We derive the expectation values of holonomies in U(1) Chern-Simons theory using Stokes' theorem, flux operators and generalized connections. A framing of the holonomy loops arises in our construction, and

Resurgent analysis for some 3-manifold invariants

open access: yesJournal of High Energy Physics, 2021
We study resurgence for some 3-manifold invariants when G ℂ = SL(2, ℂ). We discuss the case of an infinite family of Seifert manifolds for general roots of unity and the case of the torus knot complement in S 3.

A Systems Approach to Designing a Traffic Collision Avoidance Early Warning System [PDF]

open access: yesJournal of Systemics, Cybernetics and Informatics, 2017
This article examines and evaluates the systems view of the concept of the collision avoidance early warning system (will be referred to as "the early warning system" in all further instances) which uses traffic accident data and data mining algorithms ...

Hamiltonian formulations of quasilinear theory for magnetized plasmas

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Hamiltonian formulations of quasilinear theory are presented for the cases of uniform and nonuniform magnetized plasmas. First, the standard quasilinear theory of Kennel and Engelmann (Kennel, Phys. Fluids, 1966, 9, 2377) is reviewed and reinterpreted in

Lecture on Gauge Gravitation Theory. Gravity as a Higgs Field

open access: yes, 2016
Gravitation theory is formulated as gauge theory on natural bundles with spontaneous symmetry breaking where gauge symmetries are general covariant transformations, gauge fields are general linear connections, and Higgs fields are pseudo-Riemannian ...
